Clearly, SIDs are the major innovation here and they are the normal way to use Yang-cbor. 

I don’t agree the string variant should be removed. This takes Yang-cbor out of the game for “big-web” applications. 

Instead, we should make sure to explain that strings are a special option that you chose wholesale when you need it, not something you switch to from SIDs randomly.
