And that is what I said.

The good things about standards is that there are so many to choose 
from :-)
Seriously, there are WMs that where created before EWMH existed.  One
is CDE, which is used a lot.  Others in use still, are fvwm 1.x, olvwm,
mwm and KDE 1.x.

If we add a solution to Emacs that says "call this function to get
fullscreen" and then it does not work on peoples WMs, I think we are
going to see bug reports.  And if there is one response I don't like
w.r.t. things that doesn't work, it is "please change your
unrelated app/version/OS... to something else".

Exposing XSendEvent can be potentially useful for more things than
fullscreen.  For example, expand vertically and/or horizontally that
are also in EWMH.

But I do not make these desicions for Emacs, these are just my opinions.
If it is descided to put in a C-function that only works on a subset of
X window WMs, I can implement it.  But I think my suggestion is more
portable and more useful (hardly surprising :-)
