The Python core team is not really representative of the Python
community users, so I think this needs a different approach:

Instead of simply deprecating OSes without notice to the general
Python community, how about doing a "call for support" for these
OSes ?

If that doesn't turn up maintainers, then we can take the PEP 11

FWIW: There's still a fan-base out there for OS/2 and its successor


Same for VMS in form of OpenVMS:
