I don't take it as a request that you open your process to granular shot calling or feature requests from from users. Ignore them all you want! But I would put transition/succession in a different category.

Maybe in a sense requesting your project have its own life-after-death counts as "shot calling" from your perspective because it's still essentially about what "they" want rather than a sober reflection on your time/capacity/interest, but I think at least that it's different from ordinary feature requests.

It does sounds like forking is the right way to go in that case. Several successful product are forked and maintained after the original author lost interest without any involvement from them.
