Generic interfaces already exist. Generic interface methods, which would be relevant, are not planned. The reason is outlined early in the proposal: nobody knows how to implement them efficiently. Rust has the same problem, for what it's worth: dispatchable functions on dyn-compatible traits cannot be generic [1].

Or to look at that from another angle, if you were to define a Trait which has generic methods that Trait won't be "dyn-compatible" meaning that you can't do dynamic dispatch with this trait, which may be irrelevant to you (if you don't want dynamic dispatch anyway) or a showstopper (if you needed it, now your project won't compile).

		That is another way of looking at it, but given the topic, you're gonna have to expand or contextualise that. I Rust a fair bit, and only barely follow.
