The problem with adopting an ABC base class for each such use case is two-fold:
- it changes the MRO putting the ABCMeta metaclass in which might make existing subclasses suddenly incompatible; and
- is costly in terms of performance even if subclasses are still compatible.

In other words, putting ABC in isn't a transparent operation. This is one reason why it wasn't included in asyncio code.

Since we're not reacting to any breakage here, I'd feel best leaving this alone. Thanks for your care Anton!
