That's the only way to extend distutils in a meaningful way, because of the
broken command concept (e.g. the command dependency graph is defined inside
the classes instead of being defined by an external scheduler).

As anybody who has dealt with that codebase will tell you, It is impossible
to fix distutils without breaking most non trivial uses of it.
