ISTM the space saving of value of __slots__ isn't typically needed in the context of variable length built-in types.

Guido has long regarded __slots__ as a confusing hack.  That should warn us away for extending its functionality.

Unless there are some compelling use cases, a simple and clean patch, and a clear one sentence explanation for users, I recommend this feature request be closed.

Michael, do you still want this?
