I think it makes sense.

I have a use case for your fix.  Gentoo's py.test ebuild is currently
not very useful if you have both Python 2 and Python 3 installed,
because it makes /usr/bin/py.test point to Python 3 regardless of which
version the user's has picked as the default Python using Gentoo's
python-config.  (IMO this is a bug, which I reported, but it was closed
as wontfix.)  I ended up having to keep Gentoo from installing Python 3
to keep them from breaking py.test.  Your fix should make it easier for
distros to let the scripts for multiple Python versions to coexist.
