I'm not sure we need this, but if we are going to bother to have it, then it should be a target. I.e., the other side should be required to keep you full, not just not to send you any more than this.

I'm also concerned by the semantics of having exceeding the max be an error, because it introduces pressure to increase max. The issue is that what you want to have is spare CIDs, and right now the only real way to elicit new CIDs is to RETIRE, but while that's in flight, if the other side is at max it can't send more, so this makes things more brittle.
