Aye, a docs-only approach could work, and would definitely be easier
to maintain. It may just be a matter of pushing in that direction on
the PyPA side of things, by considering "requires importlib2 on Python
2.7" to be a reasonable requirement for getting some kinds of
operations to work smoothly.
