The intention was for these dicts to be used as namespaces.

By "these" do you mean type object __dict__ attributes, or *all* __dict__ attributes?

Hadn't thought of that one! Since __dict__ is widely advertised as being, well, a dict, it may be harder to enforce this for __dict__ instances of other objects. I'd like to tighten the rules here too, but only if it actually helps Python implementations other than CPython.
