I'd certainly still see there being "blessed" python releases.
(The Zope community does this in the form of "known good sets" and
these, for me, would be "the python releases")
However, it's pretty frustrating to not be able to upgrade a pure-python
package with a critical bug (as happened recently to me with httplib)
because it's part of the stdlib.
It's also frustrating to have to if-then-else about a package or
project's dependencies when using dependency management tools like
buildout when libraries such as elementtree and argparse become part of
the stdlib when they weren't before...

Breaking it apart like this would *make* the compatibility story better...
