Sort of related, what is the plan for supporting requirements which are Python 3 only packages? In particular the package: mypy-lang https://pypi.python.org/pypi/mypy-lang I was considering adding some type hints to the ironic-lib project in the future. But it needs to run the mypy program to do the type hint checking and it is a Python 3 only program. Current workaround is to put it into tox.ini.
