I like the rewording of the first sentence, but I don't think I like the new second sentence. This somewhat encourages folks to only use destination IP and port with zero-length connection IDs, and I think this might cause issues for readers that don't go look up the serious limitations that are somewhat buried in the Connection ID section. What's the purpose of the second sentence?
