I am not disputing that good can come of it, stress on "can". Let's say I'm not ready to part with a project that has been with me for more than 10 years, and for which I feel responsible. I don't want to walk away from it.
Ask me again in ten years time 
You sound like you would be giving it away never to see it again. not quite the same thing, but anyway, i wish you luck with it.
I have a little open source perl module I maintain. it's gpl licensed, and on cpan, but it still feels like mine. I mean, I still maintain it myself. I do get useful patches (and bug reports) from users though which is handy. If i decided to stop developing it, then someone else can pick it up. win win surely?
