Will the folks using forks be happy to switch to the stdlib version?
For example I can imagine that if black wants to process 3.7 input
code while running on 3.6, it might prefer a parser on PyPI even if
the stdlib version were public, since the PyPI version can be updated
independently of the host Python.
