Kindly disagree. If I don't want to work on a project anymore, I also don't want to spend time finding a new maintainer, or just take the responsibility to endorse a random person on the internet.

A fork solves that. And potential maintainers willing to work together on a fork can open an issue and talk about it. The reality being that more often than not, people think that they are willing to keep maintaining it, but in practice they just won't.
