I think this is roughly true, we could either do the simplest thing and just
add ``setup_requires`` to ``setup.cfg`` and teach pip how to understand them
and then worry about a new format later, or we can do a new format now and add
a bit of complexity to what we need to specify (though I don't think _too_ much
complexity, we don't have to define the build system stuff now, just make sure
we don't back ourselves into a corner with that).

I think either answer is OK, just the second one is a bit more work and we
might either get the start of a better format _now_ or end up regretting what
we pick when we add more things to it.
