PEP-0544 introduce typing.Protocol which allows defining an interface that can be validated on runtime.
This is currently available via a non-official extension to the typing module called typing-extensions.

Although it seems similar to zope functionality, it is very different:

1. It does not verify the arguments of the methods. Not that the implementation has the correct number of arguments and not the arguments' typing.
2. Their implementation meant for static type checking.

Can zope utilize the already existing validation implementation to also validate Protocols on runtime.
This will allow a developer to write an interface once (via a Protocol) that could be checked statically using the existing Protocol implementation and also dynamically using zope's implementation.
