We need to write text that says that receivers should:
1) check for >= 5 items.
2) always copy all items into the reply (but update the content/payload)
We discussed using <draft-ietf-cbor-network-addresses-13.txt> instead of
IP + family. (it will shortly be RFC 9164 , not in AUTH48).
It would cost 1 byte more.
if we don't, we concluded, for family to use:
