I also agree that not recognizing resets is the goal, but I don't think we're currently achieving that for reasons stated above.  And as David pointed out, I think there are allowed behaviors that would not elicit a stateless reset when you'd really like to have one sent.

Why maxcid length, not mincid length if we're trying to establish the lower bound on the packet size that could have been sent previously in the connection?  Either way, mincid+19 works for me, since I'm mostly concerned about cases with 0, or small fixed CID lengths.
