Thank you for your review.

Thank you, we can note that in a future revision.

The references

  Cheswick, W. and S. Bellovin book
  <https://cr.yp.to/djbdns/tcp.html#why>

in section 2.4 I think may largely sums up the general concern.
Maybe the section 2.4 is not correctly titled or incompletely detailed
to highlight your point.  Any specific text or additional references are
welcome of course.

Thank you.

Yes, thanks for pointing that out.  That section is still work in
progress.

Probably should be there.  Need I worry about section 6's length at
all?  It could take up a significant portion of the document given the
way this section is going.  Note, this section was added based on some
earlier feedback that having this sort of list might be helpful.

Looks potentially worth including this sort of work in section 4.

Thanks again,
