Just had a quick look at 'man cat' on Uixes I've got 'at hand'. Just a 'cut
and past' of the relevant parts.
SCO UNIX 3.2V4.2
Limitations
Note that ``cal 84'' refers to the year 84, not 1984.
The calendar produced is the Gregorian calendar from September 14 1752
onward. Dates up to and including September 2 1752 use the Julian calen-
dar. (England and her colonies switched from the Julian to the
Gregorian
calendar in September 1752, at which time eleven days were excised from
the year. To see the result of this switch, try cal 9 1752.)
Digital UNIX 4.0g
DESCRIPTION
The cal command writes to standard output a Gregorian calendar for the
specified year or month.
For historical reasons, the cal command's Gregorian calendar is
discontinu-
ous. The display for September 1752 (cal 9 1752) jumps from Wednesday the
2nd to Thursday the 14th.

Well and I would have to wonder how much the average person at the time was really tuned in with the calendars, years, etc. The church with their meticulous record keeping would've cared, as well as scientific circles (whose lines with the church were much blurrier then), but your average peasant in the field probably didn't care one way or another, so it seems like adoption of calendars at the time would've had a lot more to do with political/religious affiliation than any amount of impact on the life of an average subject.
All that to say, unlike today's modern interconnected global community, back then it was probably fine to drag your feet on moving to some new calendar because most folks weren't looking that granularly at the calendar, they were looking at the sun, moon, and stars. Of course I wasn't there, so this is all postulation, and certainly adrift from the original question so I'll resist further musings on German calendar adoption.
To tie it back, has anyone experience with cal(1) being retooled for non-western calendars, and if so, if similar problems have arisen? One country I could see being troublesome to target cal(1) for is Japan, their traditional concept of a year consists of two values, one being which emperor was on the throne and the other being the number of years since the ascension. In conventional date writing, they tend to only write the latter, mentioning the empire in the greater context to give a point of reference sure, but as a pointed example, the date stamps in the headers of several Japanese video games published in the 80s instead have a year in the 60s because it was 60 or so years after the ascension of Hirohito marking the Showa period.

Also note that the ISO country codes standard is from 1974. I guess
that is why the FreeBSD ncal states that
"The assignment of Julian–Gregorian switching dates to
country codes is historically naive for many countries."
What we call countries nowadays has changed over the years (and
centuries).

Yeah, but if you do that you have to treat the places acquired in the
Louisiana Purchase differently because they switched in 1582. And Puerto
Rico. Bleh.

To be turbo pedantic, Russia adopted a different calendar in 1918.
Gregorian and Russian calendars will diverge in 4000 CE.

That's 'ncal' from FreeBSD, which is an entirely "new" implementation

My instance of cal (MacOS 14.5) has this in the man page:
-s country_code
Assume the switch from Julian to Gregorian Calendar at the date
associated with the country_code. If not specified, ncal tries
to guess the switch date from the local environment or falls
back
to September 2, 1752. This was when Great Britain and her
colonies switched to the Gregorian Calendar.
Note that the switch to the Gregorian calendar happened at different times
in different countries. In Catholic-dominated countries it happened in
October of 1582. The English-speaking world, being Protestant-dominated,
waited until September of 1752 to adopt it.

System V Release 3.2 MRD says the same thing as SVR4:
An unusual calendar is printed for September 1752. That is
the month 11 days were skipped to make up for lack of leap
year adjustments. To see this calendar, type: "cal 9 1752"
The "BUGS" section remains the same as it was in 7th Edition.
In the CSRG SCCS files cal(1) was "updated" after the 4.3BSD release
with this comment:
src/usr.bin/cal/SCCS/s.cal.1

Solaris 11 has this version:
NOTES
An unusual calendar is printed for September 1752. That is the
month 11 days were skipped to make up for lack of leap year
adjustments. To see this calendar, type:
cal 9 1752

Just what I wanted; many thanks. And I couldn't remember what SysV said,
but I did know that they changed it.

Looks like on the BSD side it disappeared between 4.3 Tahoe and Reno. It's
in research through v10. It's in SVR2; SVR4 modifies it to say "An unusual
calendar is printed for September 1752." I don't seem to have manpages
with either of the SVR3 source distributions that I have handy. So to
answer your basic question, it stayed around for quite a while.

It's still mentioned in the latest version of FreeBSD:
-s country_code
Assume the switch from Julian to Gregorian Calendar at the date
associated with the country_code. If not specified, ncal tries
to guess the switch date from the local environment or falls back
to September 2, 1752. This was when Great Britain and her
colonies switched to the Gregorian Calendar.
It sounds like that's not the quote you're thinking of, though. I've
checked back as far as FreeBSD 1.0, which had a much simpler version
of cal. The man page states
The Gregorian Reformation is assumed to have occurred in 1752 on the
3rd of September. By this time, most countries had recognized the ref-
ormation (although a few did not recognize it until the early 1900's.)
Ten days following that date were eliminated by the reformation, so the
calendar for that month is a bit unusual.
Maybe you can find something more interesting in the TUHS archives.
