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.)
