Good, so maybe take this discussion to distutils-sig first?

Virtualenv allows you to create an isolated environment to install
some distribution without polluting the
main site-packages, a bit like a user site-packages.

...as does buildout, and these are the right type of solution to this problem.

My opinion is that this tool exists only because Python doesn't
support the installation of multiple versions for the same
distributions.

No, it exists because per-project specification of requirements is a really good thing. Having multiple versions of the same package in the same python environment it totally batshit crazy...

Setuptools provided a multiple version support but I don't like its
implementation and the way its works.

See the "crazy" comment above...

- a special import system using importlib that would automatically
pick the latest version, thanks to PEP 376.

As long as I never have to use it or see it, I don't really care, but this seems like creating more work for yourself and another gun pointed at the face, nevermind the foot, of the unwary newbie...
