Yeps, that was the general tone of some thread on python-dev. And from 
what I saw of the source code, it may effectively not be the cleanest 
part of the stdlib. But what, it does what it was written for at first : 
provide working support for zipped packages.

Seems like Bob Ippolito was on the rank, but I guess you'll get better 
answers on python-dev.

Indeed !-)

But while having zip/unzip installed OOTB on a unix-like system is close 
to warrented, it may not be the case on Windows.
