All good points.

Perhaps a better solution for open source packages is to distribute
exactly the version you test with (which you may have patched), with
the caveat that users who use other versions are on their own.

That's one of the beauties of open source; you can insulate yourself
from all the maintenance issues just by distributing the version of
the source you happened to use. 

I would hope you would make an effort to contribute fixes and upgrade
to later versions, but there's really no need to require your users to
do that on their own!
