[Distutils] Plans for a build command or --user support for pysetup3?

[Brett Cannon]

I just tried creating a setup.cfg for coverage.py as
distribute_setup.py was hanging when run by Python default (worked
fine when I installed it directly). Two things that I missed was
wanting a build command (having trouble compiling coverage.py's
extension module) and --user suport for install.

Are either of those planned or in the works? If not, any specific reason why?
