Not sure this is the same thing a what you want, but I do have a 
pipedream of rewriting configure in Python.  At this point it has a lot 
more logic than it has command invocations.

John, do you think it makes sense to do the "pip install" steps already 
in mkvenv's post_post_setup phase?  Maybe by passing a version spec like 
meson>=0.61.5 in place of the simpler "--gen pip,meson,sphinx" that you 
have now?

Not for this series; just dumping some thoughts prompted by Daniel's 
question.
