As there was no further comment (except for Stephane's hint that the the
general reaction was along the lines of "you mean we used to do
*what*?") I've committed this.

I wonder if it's worth adding an option to emulate so you can "emulate
-v 4.2"?  It would be highly imperfect since only the MULTIBYTE and
KSH_ZERO_SUBSCRIPT options are useful for this purpose; you're stuck
with anything else.
