Yes. Let's count the ways:
* our shim breaks every time someone does something new with glib2
features (see the demo-mp3.c in plugins/gst/playondemand, compiles with
glib2 but our macro shim is broken for 1.2, and no one's bothered to fix
it because developers mainly use glib2 now)
* the insane utility of GValue type conversion routines
* auto initialization of parameters according to paramspecs: we can't do
this with the shim
* bounds checking on paramspecs
* REFCOUNTING! this is the big one.
the list does go on. i am tired of gtk1.2. let's get our apps ported so
we have no more excuses.

Right. if folks really don't want to upgrade to glib2 (for which there
are packages on every major distro afaik), they can stick with our next
release. I'm not really excited about backwards compatibility at this
point, especially when glib1 and 2 are parallel installable.

After the next one? That would be right nice.
