I will maintain ownership of the repository, but I won't pass it down to anyone else. First, because I feel it's not up to me to decide who to pass the project down to, and second, because there is no one else to pass the project to.

I vaguely remember some money calculating-related project guy who received a PR that heavily optimized and updated the project. Since he was very busy and no longer really wanted to maintain the project, rather than reviewing and merging the commit, he gave the contributor complete access to the repo for them to maintain the project at their own discretion. The project was unpopular back then—when he looked back a few years later, he was surprised to discover that the project had racked up several thousands of stars.
