I've got s pretty great solution to this kind of stuff, one that works for me anyway.

If I want something that doesn't exist bad enough, I make it. I release it to the world for free. When I need an improvement, I make the improvement. If you need an improvement, make a PR. If it's a feature request, unless I think it would be interesting to implement, make the tool more well rounded or I will find utility in the proposal, I don't do it.

I don't maintain beyond that. Sorry not sorry. If it's popular enough that a community forms around it the community can maintain it. If someone or some company comes to rely on it, they can maintain it. I made a thing, I gave it to the world for free just because, that's it. I don't owe the world anything and I'm not a charity.
