> As to resets, perhaps they do not make sense for short CID's.

I would rephrase that to a question: do we need to give (some small number of) implementations a chance to save 3 octets, even though some features will not work if they choose to save the bytes?

I do not think it is something worth doing.

Note that in the future we could introduce very short CIDs *for short packets* in future versions of QUIC, even though we decide to not have them in QUIC v1.
