Yes, we had a few cases like that, esp. with declarative as it depends on
some internals in QtCore/Gui. But these breakages have started to happen
less often, so I’m less worried about them now than I used to be.

IMO qtbase is a bit too large now as it is. We often have too many changes
being staged at the same time, and CI runs failing because of this making
it hard to get things into qtbase. So helping qtbase CI runs will IMO make
things more productive overall.
