I believe the documentation side of things is an acknowledged gap, people just need
to actually write the documentation, e.g. Boris and Thomas documented the tip-tree
under Documentation/process/maintainer-tip.rst and stubbed in maintainer-handbooks.rst.

As for patch lifecycle, I would love to have something like tip-bot (can we just
steal whatever scripts they use?) that explicitly calls out the branch, commit,
committer, date, etc... IMO that'd pair nicely with adding kvm/pending, as the
bot/script could provide updates when a patch is first added to kvm/pending, then
again when it got moved to kvm/queue or dropped because it was broken, etc...
