Given that your choice method for sets would be little more than

    value = random.choice(tuple(s))

it seems like it's probably overkill to build it into Python -
particularly as doing so restricts the implementation to Python 3.6+
whereas writing it out by hand works for any version. It also makes
the complexity of the operation explicit, which is a good thing.
