Yes we could add a flag for it. However, for the two users that I'm looking at right now (algif_skcipher and sunrpc) this is not required. For algif_skcipher it'll simply fall back to the current behaviour if chaining is not supported, while sunrpc would only use chaining with cts where it is always supported.
