Are the undocumented member functions of `random.Random` supported?

Documentation

The documentation for random.Random really only discusses the member functions subclasses should override. However, it never mentions, nor documents, the functions that the class provides. For example, Random.randint exists; is it supported by Python to call that? (E.g., is random.SystemRandom().randint(…) a supported call?

If so … could these be documented?

[picnixz]

They are implicitly documented in:

The functions supplied by this module are actually bound methods of a hidden instance of the random.Random class. You can instantiate your own instances of Random to get generators that don’t share state.

IOW, module-level functions have their counterpart as methods, but we don't want to rewrite the same documentation.

As for whether SystemRandom(...).randint() is supported, yes, it's a legitimate call.
