Presumably this could enable a more streamlined packaging and publishing of
the test suit (e.g. to PyPI). But I agree, right now it is not really
needed given the downsides, I just brought it up as an extreme separation
case to collect more opinions.

Given the feedback we have in the thread, I will proceed with the first
point as this should have immediate benefit for the duration of the test
job and already give help to those who want to package the test suit
separately. Distutils stuff can be added later.
