If anyone else needs it, they are free to copy and use it. If they find a problem that I think needs fixing or my stuff will cause me problems, I'll fix it. Otherwise, they are free to fix it and(if kind enough) submit it.
I have 0 obligation to fix anything that I don't personally need and anyone that copies it has 0 obligation to give me anything in return. I only published it to save someone else the time for the bulk of the work. I'm not doing it for money or cred. I do it because it's something I already finished(more or less) and it won't cost me anything to share. Anyone elses needs(family and friends exempt) are not my problem unless It's my (paid) job to make them my problem.
