A use-case for writable bases:

__init_subclass__ is called in type.__new__, which means that for Enum __init_subclass__ is called before the members have been added.  To work around this I am currently (3.10) adding in a _NoInitSubclass to the bases before type.__new__ is called, and then removing it.

A better solution to that problem would be a way to tell type.__new__ /not/ to call __init_subclass__, but I don't have that option at this point.
