You already don't need to list the attributes from the base classes.
The __finalattrs__ are converted into class level descriptors, so if
class D inherits from class C, it has the __finalattrs__ descriptors
for both classes.

Did you try it and find that it didn't work?

I'm not *in*-sane. Indeed, I am so far *out* of sane that you appear a
tiny blip on the distant coast of sanity.
