The greeter doesn't set anything, it gets the menu selection and gives
it to lightdm.

Well, this one is a problem, it's should not be the case (and it's not
the case for me on any of my box).

Indeed, I missed that.

My guess is that they get used by GNOME applications.

If you look really really hard, you'll see that LANG is set on the
previous line.

Since lightdm set GDM_LANG to the exact same value as LANG, I fail to
see why it's not set to the correct value at the beginning of
/etc/X11/Xsession, but at least that gives you something to look at.
