Interesting-- so move to a Python specific binary distribution option
-- rather than using rm or deb packages?

Doesn't lead to a dependency heck? I.e no way to express non-python

And while we are moving forward, can we please deprecate dependency
management and installation from setuptools?

Is there a philosophy of intended separation of concerns articulated somewhere?
