The way I look at it is that releasing an open-source library is like bringing a child into this world: its utmost well-being is your responsibility. If you don't have the bandwidth for that, don't publish it. And, if your circumstances change later, find another maintainer -- after all, you wouldn't just abandon your child on the street, would you?
It's not a child. It's a hammer. Somebody put it in the community shed so others can use it. If it breaks or somebody needs a nailgun, that's not their problem. I'm glad if somebody lent me their hammer so I don't have to buy one, even if it's not the best.
