Obviously yes, as neither buildout nor setuptools would exist otherwise. ;-)
Nor would Fedora be packaging certain library versions as eggs
specifically to get certain multi-version scenarios to work.
The specific solutions for handling n*m problems aren't fantastic,
but they are clearly needed.
(Buildout, btw, actually hardwires the n*m choice at install time,
which is probably better for production situations than setuptools'
dynamic approach.)
