*I assume we ultimately need a committer to review the work of anon-committer ahead of merge ( since someone with permissions eventuallyhas to actually accept/merge/commit the code ). In general, is onereviewer/committer sufficient?* IMO, yes, one reviewer who is also a committer is sufficient
*How does this change if the author of the PR is an existing committer?* If I am a committer and I make a PR, I would wait for another committer to review and approve. However, if it's been a week and no one approves, I would send a review request to dev@, and if there is no response after a couple of weeks, then I'd go ahead and merge it myself (given all tests/checks have passed of course) Thanks for the discussion! - Gedd
