I've seen the occasional .Z file in recent years, but never that I 
recall for a Python package.

As plugging in external compression tools is less likely to work 
cross-platform wouldn't it be both easier and better to deprecate (and 
not replace) the compress support.

If there is a huge outcry adding LZW support to tarfile can be reconsidered.
