This is a feature request by a user at https://github.com/python/typing/issues/822. A copy of their request: Currently issubclass cannot be used for runtime_checkable protocols with data members, because those attributes could be set in __init__. I propose to relax this restriction to allow protocols with ClassVar members, as those should be present in the class definition. I'm unsure if I need to update PEP 544 too. I don't remember if PEPs can be updated when 'Accepted', or was it 'Final' PEPs that can't be updated anymore?
