[Python-ideas] Add MutableSet.update?

I was trying to use `collections.abc.MutableSet` today, and noticed that it
does not define an `update` method. This is a very useful method that is
present on the builtin `set` class, and seems to fit naturally with the
other methods.

Was omitting this method intentional?

Thanks & best wishes,
