[ST] Section 10.2 says, “IANA responded to the early allocation request with the following TEMPORARY assignment:” and states that the allocation expires on 13 December 2022. However, on 13 December 2021, the determination by the port experts was that the existing port would be modified when the document was approved for publication, not that an early allocation or modification would be made. Can this section be rewritten to reflect that a modification is being requested by the document?

[ST] If a port allocation is required here, please clarify what the IANA actions should be.
