For the sake of fairness, I leave here a record of a benefit obtained
from trying to keep support for xemacs.  The dicovery of the series of
bugs I reported about font-latex.el[1] were triggered by the warnings of
byte compilation in xemacs.  Since GNU emacs doesn't warn about those
code, the bugs were left unnoticed for a fairly long period if I didn't
test with xemacs.  In this sense, it is not bad to have two different
byte-compile optimizer at our hands.

Having said that, I also agree that such benefit is too small compared
to the burden of maintaining support for xemacs.
