haha... it would be awesome if they implement it in the 'future' .. i
posted the same to python-dev at python.org, it seems the distutil is
getting a big overhaul. (i hope they make a new uninstall option for
setuptools n easy_install) they say there are many ways to do that
using pkg tools... but python wants one and only one way- the python
way.
regarding issues:

1.security is always a issue
2. regarding problems like with statement you mentioned earlier.. i
think there will be a basic feature set that is common for all
versions of add-on libraries.
3.when you want the new feature you have to update your python
interpreter

use interpreter 1.5.2

may trigger the proper interpreter plugin(responsible for additional
feature) to load and add functionality.. its simple to say but it is
hard to make the compiler pluggable, may be they figure out.

use library x.y.z

while issuing this command the default interpreter has to
automatically resolve dependencies of the core c/cpp static libraries
and other shared libraries. so that must not be an issue. if they have
implemented this much, dep solving is nothing.

futuristic python may also contain an option for compiling a module
into a static library. so we can code python libraries in python
(mostly) itself. think of pypy. it is already state of the art.
