Sure. No problem with that.

For recognised but unsupported features requested in the ConnRqst, the 
router would still send a ConnRply though, right?

Absolutely. As you mentioned, the client library doesn't have much choice 
(or the choice is fairly obvious). I was just pointing out that the 
suggested NOT_SUPPORTED (a libelvin API error code) is not what that 
implementation would (or should) report to the application.
