FWIW, I'm less convinced that moving away from Bugzilla is a good idea.

It might be, I just don't know yet.

One really nice thing is that it actually has a view of outstanding
patch series, that's properly tied to things getting committed, unlike
patchwork which is only useful if people bother to curate their series'
status.  I'm struggling to keep up with mesa-dev these days, despite it
being my day job.  Having a page with the series outstanding might make
life easier for reviewers, and also make it easier for series not to get
lost and fall through the cracks...

Mechanically, it also had pretty reasonable support for multiple patch
series, updating a previous one automatically (IIRC).

One thing I hated about using Gitlab for the CTS is that every series
created merges, littering the history...and worse, people got in the
habit of only explaining their work in the pull request, which became
the merge commit message.  People didn't bother giving individual
commits meaningful explanations.  That made 'git blame' harder, as
you had to blame then look for the merge...makes bisects messier too...

Maybe that's what you were getting at.  I think discipline can avoid
that, but we'd have to be intentional about it...
