Please note that we are not yet ready to upgrade pygobject to its latest 
upstream versions: that will regress an unknown number of dependent 
packages, due to it having moved from libgirepository 1.x to 2.x. See 
#1099164 for details, and in particular note that this is entangled with 
applications that use libpeas, such as gnome-builder and liferea, which 
will have to either all move as part of the same transition, or 
temporarily drop support for Python plugins, or be temporarily removed 
from testing.

The move from libgirepository 1.x to 2.x in pygobject will probably have 
to be handled as a transition; but the GNOME team is already waiting for 
a transition slot for the smaller GLib 2.86 transition (#1115340), which 
should be done first, and then another transition slot for GNOME 49.

So if the python3.14 transition is to happen any time soon, it is likely 
to be necessary to backport the fixes for test regressions, rather than 
just updating to a new upstream release.
