"Zero maintenance" is an exaggeration, IME.  Not every code fragment
that uses these compatibility shims is as clear-cut as the snippet
above; more often than not, when working on code which references
those shims, one needs to dig quite deeply into the sources until
he/she understands that the code is a no-op in Emacs.  That digging
takes/wastes time and effort.

I'm sorry, but that ship has sailed several months ago.  Gobs of
XEmacs compatibility features were removed already, after the removal
move was announced.  Are you saying we should reinstate all of them
back?  If not, what is so special about this particular one?
