I don't think this is needed nor do I think that it is a good idea to have a copy() method in the ABCs because they know so little about their concrete underlying class (perhaps the backing store in the filesystem or a database). Besides, a user already has workable alternatives such as creating a new instance and applying |= to populate it.
In general, we don't do API expansions without motivating use cases to guide the design.
Also, note that MutableMapping does not have a copy method. |
