I'm not sure how much extra maintenance it would be. Sure, it would take
some work to get the parallel packages setup initially, but I'm not sure
it would be that much work after it is already set up.

I don't have a whole lot other than I think it would be better to have
GTK+3 support sooner rather than later so that non-X11 backends (e.g.,
Wayland) can be supported.

I'm not optimistic about 3.2 being any time soon. It seems that upstream
development has slowed recently - well, not necessarily development
itself, but releases. Ie, they've been talking about a 3.0.3 release
"coming soon" for quite a while now and there doesn't seem to be a lot of
The other reason I'd propose parallel packages is that I think moving some
applications to GTK+3 is going to take a bit of work (and thus, the work
would not *have* to happen within a release cycle). Unfortunately, in
GTK+3 the size of some widgets has increased (e.g., GtkSpinButton now has
the plus and minus buttons side by side instead of stacked) and
applications that have hard-coded widget sizes, or not enough space
allocated have problems.
