True but the difference is that six is widely used enough to be packaged
in most distributions, I guess.

Also, I expect whatever version of six to work quite smoothly while
imaplib2 can introduce very subtle bugs.  Offlineimap is a big wrapper
of imaplib2 and bug reports with unexpected versions of this lib would
be challenging.

I'll consider this idea. Though, "Latest" is not what I'd like since
they might be broken too.
