The topic of a review workflow comes up frequently, but Gitlab, Gerrit, etc. are blocked on a host of other problems that may never be resolved. It would still be nice to be able to request reviews somewhere, and for ebuilds, a mailing list combined with a threaded MUA works fine.
Would anyone else find gentoo-review@lists.g.o useful? I think a lot of simple problems could be quickly caught with a second set of eyeballs. There is already gentoo-dev-help@, but it's /very/ quiet. If we could all agree to subscribe and do reviews there, that would work as well.
