[Distutils] Changing the separator from - to ~ and allow all Unicode alphanumerics in package names...

Although I think the ~ is a very ugly -, it could be useful to change the
separator to something less commonly used than the -.
It would be useful to be able to use the hyphen - in the version of a
package (for semver) and elsewhere. Using it as the separator could make
parsing the file name a bit trickier than is healthy.
This change would affect PEP 376 which reads:
This distinct directory is named as follows::
name + '-' + version + '.dist-info'
with today's hyphen/underscore folding: re.sub('[^A-Za-z0-9.]+', '-',
version), could become
It would also affect pip, setuptools, and the wheel peps. If we do this, I
would like to allow Unicode package names at the same time. safe_name(),
the pkg_resources function that escapes package names for file names, would
re.sub(u"[^\w.]+", "_", u"package-name", flags=re.U)
In other words, the rule for package names would be that they can contain
any Unicode alphanumeric or _ or dot. Right now package names cannot
practically contain non-ASCII because the setuptools installation will fold
it all to _ and installation metadata will collide on the disk.
safe_version(), presently the same as safe_name() would also need to allow
+ for semver.
Does anyone have the energy to actually implement a proof-of-concept?
