people still make .xsession? wow... :)

This is the concept we've implemented in uxlaunch and I strongly agree
with this. On top of that, it's also what Gdm does... Deviating from
this doesn't make much sense - it's just the better place.

well, I'd really try and not tell people to use either Xsession or
xinitrc.d stuff. Nobody knows how it works, distro support is probably
sparse, and on top of that any alternative to gdm should get this
reasonably right, just like I'm trying to do with uxlaunch...
