The same issue exists with *any* method that you use in
a cooperative super call. You need to ensure that there is
a class at the end of the MRO with a method that terminates
the super call chain.

It's obviously infeasible to add all such possible methods
to class object. You will have to provide a *very* strong
reason why __getstate__ and __setstate__ should be singled
out for special treatment in this regard.
