At the moment, yes, it could affect partial upgrades. I was going to give
gir1.2-gweather-4.0 a Breaks: gnome-shell (<< 42) to prevent the
known-broken partial upgrades from happening, unless you consider the cost
of those Breaks to the apt solver to be higher than the risk of broken
partial upgrades.
There are probably other scenarios where a partial upgrade from bullseye
to bookworm will break bullseye's gnome-shell. I can try to scatter enough
Breaks through our ecosystem to prevent those, but it seems unlikely that
I'll find all of them.
Because testing is already broken (it's too late for a gir1.2-gweather-4.0
change to fix existing systems immediately), and partial upgrades are
not really supportable in general, I had been prioritizing like this:
1. fix full upgrades to testing by getting Shell 42 migrated
2. fix Shell upstream so this won't happen again in 42 -> 43
3. (please mind the gap)
4. a best-effort attempt to stop the breakage that already happened from
affecting partial upgrades
