@alcinnz @nihilazo @calcifer It's not hard to make the situation clear in the README file in my experience. Not much different from the situation when the developer needs to stop providing support after some event in their life.

Publishing it may give someone else a jumpstart in their own project and it would be a shame to keep that from happening just because you are 'throwing it over the wall'. You don't know if someone is on the other side ready to catch it!
