Steps to reproduce

I'd like to have a single class implement both IFeedbackProvider and ICommandPredictor, however, because ISubsystem.Kind is internal, I can't specify it.

I suppose one option is to introduce a new IFeedbackProviderCommandPredictor interface for this purpose which can internally set ISubsystem.Kind to the right value.

Expected behavior

Able to implement both IFeedbackProvider and ICommandPredictor in a single class

Actual behavior

Fails to compile because there isn't a single implementation of ISubsystem.Kind
