Noting an abstract connection does not mean there is a practical one.

The current draft provides information that is necessary and sufficient for understanding and using the field.

If you think otherwise, please explain carefully, since I think there is no other indication of technical problems with the draft.

The example provides sufficient tutorial context to make the understanding and use concrete and accurate, as far as I can tell. And I believe that no one else is expressing a concern, so far.

As for possible interactions with other fields, again, the instructions in the specific are quite simple and pointed. And sufficient.

Introducing commentary about secondary issues invites readers to be confused or to debate matters. Absent normative import -- and especially absent demonstrated implementation or operational issues -- adding such material mostly has downsides. At best, it's simply extraneous and ignored.

To the extent that discussion about broader issues with header field creation or use is needed, such material is suited to a broader, systems-oriented document.
