Why not get the interpretation from 6man WG since RFC8200 is one of the outcomes of 6man WG?

(5) This point is for the IESG to discuss.

§4.16.1.2:

      The End, End.X and End.T behaviors with PSP do not contravene
      Section 4 of [RFC8200] because the destination address of the
      incoming packet is the address of the node executing the behavior.

The spring WG's interpretation of rfc8200 was a central point in the appeal
presented against the WG consensus on this document.  The text above, I
believe, reflects that consensus.

However, given that the document relies on the spring WG's interpretation of
rfc8200, I think it would be better if the text is explicit.

Suggestion: to add at the end of the paragraph>

   This conclusion represents the consensus interpretation of the spring WG.

This seems like an important -- and entirely reasonable -- thing to note.
