Perhaps to say that the peer MUST NOT consider the connection IDs it has been asked to retire when calculating whether the limit has been exceeded, even if they haven't actually retired them yet?  That gives implementations the latitude to hang onto them for a bit if needed, but keeps you from going over the limit even so.

Then it's the implementation's business whether it wants to defer adding the CID (and block processing of this frame), add it and exceed the limit temporarily, retire the old CIDs on the spot, or something else.
