I agree although reluctantly.  A downside of doing
a lot of configuration (even linking) at dynamic
session creation is the behavior that occurs when
there's an out-of-resource condition (e.g. no disk
space).  The less we have to do "on the fly" the
more robust our solution.

That said, if we plan to configure different types
of sessions for different displays, we're forced
in that direction anyway.

It should be said that the code we've added is in
the main GDM branch today.  We're just waiting for
some distros to catch up, and providing our own
version until they do.  Unfortunately, because we
can't provide built versions to match every
distro/patch rev we're sometimes forced to
actually down-rev the distro's native version with
a version we built with our fixes merged from the
main trunk.  It'd be a bit much to expect everyone
to build GDM from scratch at SRSS installation
time :) Not to mention unsupportable.
