Not quite the same thing. -newerXY allows you to compare for example the 
creation time to the access time (not sure *why* that would be useful, 
but it is possible) or any other such permutation. the -Bnewer/-mnewer 
etc doesn't seem to support such mixing.

As for versions, according to the man page of GNU find (4.9.0) on Arch 
Linux, in the HISTORY section, -newerXY has been around since version 
4.3.3, and "also occurs in BSD".

3. Another issue: Missing completion

When reading the GNU find man page HISTORY section it seems that a new 
flag was introduced in 4.9.0, which should probably be supported in the 
completion:

-files0-from file
     Read the starting points from file instead of getting them  on the
command line.  In contrast to the known limitations of passing starting
points via arguments on the command line, namely the limitation of the
amount of file names, and the inherent ambiguity of file names clashing
with option names, using this option  allows  to  safely  pass  an
arbitrary number of starting points to find.
[... this section is quite long in the man page, I suggest looking at 
for example https://man.archlinux.org/man/find.1 if you don't have it 
locally and want to read the full thing ...]

Something like:
'-files0-from[search NUL separated paths from FILE]:file:_path'

should do the trick.

The feature before that and -newerXY (-D, added in 4.3.1) seems to be
supported by zsh completion. I haven't checked if all older features
are also supported.
