It'd be neat if "Merge when ready" expires after some amount of time. Setting a PR to merge when ready feels like a time bomb if the PR doesn't get merged for a long time... maybe people put off reviewing, and by the time it's approved, it functionally conflicts with code that's landed in the interim. (By the way, I'm assuming that if everything is green and I'm waiting for a reviewer to stamp it,

merge when ready

will merge when the PR is approved... I haven't seen it happen yet, so LMK if my understanding is incorrect)
