I briefly discussed the possibility to merge the two drafts with the
2988bis authors in June but we didn't reach a consensus. One reason is
that this draft updates 5681 in addition to 2988. Since the submission
deadline was less than two weeks, I decided to send draft alone and
see tcpm's opinions.

Do other people on tcpm prefer integrating the two drafts (and
adopting it as one WG item :)  ?
