Do you think that a trivial, 4-line commit to README saying "this project is no longer maintained, look elsewhere" is too much to ask? I agree that you cannot force people to give their time away, and anyone can, and should be able to, stop maintaining any project they have. But putting "I am done" notice will likely take under 30 minutes, and will help a lot of people. It's a good idea to do it just out of respect to all those people who spent their time crafting those 669 commits which will never get to release now.
