[Note, that I am just talking as individual here, these IANA actions
do not relate the IKEv2 registries where I am IANA Expert]

I proposed to change both the UDP and TCP references for the port
4500, as even if the RFC3947 did do the IANA actions, it does not
describe the protocol used on the port. RFC3948 and 7296 does.

So from my previous email I would suggest following text:

----------------------------------------------------------------------
  14.  IANA Considerations
       
    This memo includes no request to IANA.
       
    TCP port 4500 is already allocated to IPsec for NAT Traversal.
    This port SHOULD be used for TCP encapsulated IKE and ESP as
    described in this document.

    This document updates both TCP and UDP references of the port 4500
    to match the current protocols used on those ports:

    Keyword       Decimal    Description          Reference
    -------       -------    -----------          ---------
    ipsec-nat-t   4500/tcp   IPsec NAT-Traversal  [RFC-this-rfc]
    ipsec-nat-t   4500/udp   IPsec NAT-Traversal  [RFC3948], [RFC7296]
