The upgrade process is going to be somewhat tricky. I'm not sure
exactly how it will behave (it'll depend on whether the F22 version
depended on any libraries that had an ABI break on F23). Adding the
ability to automatically-enable the COPR is a very difficult problem.

We may in fact actually want to arrange it so that the package is
completely removed on upgrade (so that users can then go and get it
from GNOME Software again). Not an ideal solution, but perhaps the
only one that could be accomplished in the remaining time.

Unfortunately, this is a classic problem for retired packages. I've
often wondered if Fedora shouldn't have a special meta-package in the
repository (installed by default) that Obsoletes: packages that have
been retired (thereby ensuring that they are removed). But this is
getting a little off-topic.

The short version is that what will likely happen is that the old
version will remain if it meets the deps or the upgrade will fail its
dependency check and not be possible to run until the offending
packages were manually uninstalled.

Done right, it should be pretty much the same experience as if it was
in the official repos, except with a click-through acknowledging that
it's not coming from us, but a semi-official third-party.
