Cool. I'm not that familiar with those tools, but if they enable that
sort of use then that's great. I did get the impression that they were
for more complex/specialised use cases, though, whereas flit (with PEP
517) is much more about simple configuration for the majority of (pure
Python) projects that don't need complex behaviour.

But that's mostly about target audiences than capabilities.

One thought - are the PBR and/or distutils2 teams looking at providing
PEP 517 support? Assuming they are, have they had a change to review
the PEP to ensure it suits their needs? And if they aren't, what is it
about the PEP that makes them unwilling to do so?
