But that's a reason why the site-packages should be moved to the end of
the paths that are prepended to sys.path:

When pinning a package to a specific version, it may end up *not* being
used, because site-packages has the same package with a different
version. If site-packages is at the end, that problem goes away.

Can this be implemented or is there a technical reason for not doing it?
