One of the things with mailing list driven workflow (in Guix and RDE) bothering me is that I can't review and merge patches without downloading emails, applying patches locally, signing them and pushing them to repo.
However, for most version bumps and other trivial changes it must be much more convinient, just one button click away. If it was so, it would be much less stale and forgotten patches I guess.
Most of git forges do much better job here.
@abcdw They do a better job, except when the committer is required to sign commits, as is the case in Guix; in that case the forge still leaves it up to the committer to perform the last actions.
