I thought that the list in the PEP seemed reasonable:

python setup.py dist_info
python setup.py sdist
python setup.py build_ext --inplace
python setup.py test
python setup.py bdist_wheel

Most projects already have a setup.py that can do these things with
the exception of bdist_wheel. The only ambiguity is that it's not
clear whether the expectation is *exactly* those invocations or
whether any other command line options etc. would be needed.

Can it not simply be documented that these are the commands needed by
current packaging tools (and return codes, expected behaviour, ...) to
fit with the current bleeding edge infrastructure?

I would have thought that that would be good enough as a stop-gap
while a better non-setup.py solution awaits.
