Commiserations but at least Xlib today is back compatible. Try a 25 year
old windows app and weep.

Probably not although I suspect the need to provide accessibility in much
software today is finally burying the hatchet.

There shouldn't be any breakage of compatibility in old old apps. You may
have problems with fonts and with some extra libraries where the
distribution vendors no longer ship those extensions by default or at all.
That is much more a distribution change and since extensions are exactly
that quite allowable (if annoying in some cases)
