I think the document is basically ready for publication, however, I have two comments/questions. tThe first one is more a suggestion but the second point is something I think we should be should we have support for in the group before we move ahead.

Looking at the diff, there was a section in the security consideration about information sharing of application-specific settings. So why was that removed? However, I think the document could even say more!

I'm okay to discuss more considerations on the IW e.g. on the design principle level and most importantly maybe that a loss within the IW can/should impacting the cached value, and to do so even in the body of the doc, however, if I remember correctly there was a lot of discussion about the automated setting of IW in tcpm when the IW10 RFC was under discussion and no agreement reached in the group, so would rather just like to see a reference to the expired draft than copy and pasting the whole algorithm in the appendix of this draft.

The discussion was only whether there were specific settings that had been implemented. If we cite an expired draft, we need to basically add some info to explain what’s in the other doc (which we are supposed to treat as non-existent). I.e., if we’re citing an old draft for credit, it’s just a citation, but in this case we’re saying that the techniques in that draft *are* just a variant of what 2140 already suggests, only on a different timescale.

I.e., “discussing more considerations” is basically what that text already does. All the issues that are in the original doc were relevant for this one’s discussion on that issue.
