I think it can be easily solved much like a normal bug fix - upon instance creation and before throwing an "ABC doesn't implement..." error, recheck the class __dict__ or even mro using hasattr, and only then throw the exception.
It will slow down only the specific course where the methods were defined dynamically. Plus it'll support dynamic __getattr__ on a child metaclass as an added bonus. Bar Harel.
