OK, I'm sorry, I didn't get it that this was an anti-pattern, thanks
for explanation (to both you and Ryan).

I guess this then changes my question into: how could we get rid of
these two rows?

    master_sites        pypi:[string index ${python.rootname}
0]/${python.rootname}
    distname            ${python.rootname}-${version}

We still need to keep in mind that some ports might prefer to fetch
python modules from github for whatever reason, so it needs to keep
working in cases like those.

Maybe something along the lines of "python.use_pypi yes" which would
set the two?

Thank you,
