Asking directly, because I could not find a straight answer: What happens when a maintainer goes quiet
Nomination for promotion into the documentation commons, with the criteria addressed one by one.
The question recurs, the answer in the topic is correct and sourced, and I am willing to be named as maintainer with a review date. That is three of the four; the fourth is whether anybody objects.
Objections genuinely wanted. A bad promotion is much harder to undo than a bad reply.
