Creating and using a virtualenv is, in practice, _easier_ than any of
those alternatives, so it's hard to see it as "overkill." Not to mention
that the "isolation from system site-packages" feature is quite popular
(the outpouring of gratitude when virtualenv went isolated-by-default a
few months ago was astonishing), and AFAIK none of your alternative
proposals support that at all.
