Why don't you pass over the maintainer role to some of the users of the project?

Or share the maintainer role with some other users. Just select one, two, or three people who seem to be responsible and give them all the necessary write access.

Or maybe configure the repo in a way that all PRs need at least two (or so) reviewers from a selected group of reviewers.

Then this would greatly reduce the effort on your side, and development should continue on its own.
