The point here if you read contributor comments is mainly to allow people to shut a PR down without having claims of “unfairness” because some other PR wasn’t shut down. These are “moderation policies” in the style of old internet forums, their primary purpose is to clear up ambiguity and make maintainer’s (moderators) lives easer.

The birth of vibe coding has seen interactions on public FOSS projects increasingly reminiscent of the flame wars and moderator hammers of the old forum days. A lot of projects have been behind the curve on preparing and codifying the hammers, probably because no maintainer really wants to be a moderator, but thats where its naturally landed unfortunately.
