"Premature" is a weird term to use here, considering the
whole point
of these things is to be able to do integration work in the first
place. And it's not like we can't revert the change before release if
it turns out to be problematic.
Yes, premature as in proposing a huge change to the next version of Fedora before ensuring
current users can even test/evaluate said change. The fact that there are packaging
conflicts when installing pipewire-pulseaudio strongly suggests that few people have
actually been able to install and test the package.
