Re: [auth48] AUTH48: RFC-to-be 9494 <draft-ietf-idr-long-lived-gr-06> for your review

[Megan Ferguson <[e-mail]>]

Hi John,

Thanks for sending these changes along.  

Just a few notes:

1) w.r.t. “period of time”, we see ~1400 uses in past RFCs, so we have left this as was.  If your preference is to update to “time”, please let us know.

2) w.r.t. the section titles, we simply tried to keep them brief to keep the Table of Contents useful and concise.  Again, just let us know if the originals are preferred and we can revert them.

Please review the files carefully as we do not make changes after publication.  

The files have been posted here (please refresh):

Please contact us with any further updates/questions/comments you may have.  

We will await approvals from each of the parties listed on the AUTH48 status page prior to moving forward to publication.

In this case, I think the edit makes the intent unclear so I’m requesting the edit or explanation.

There are also a few other “period of time” that could probably be cut down, but at some point, ya gotta say “good enough, ship it". If you want to propose edits for those as well, that’s fine, but it’s also fine not to.

If you think it’s very important, of course, “better late than never” applies to fixing serious protocol errors. But my first reaction is that this isn’t a serious error, just a design choice that we might have wanted to reconsider had we discussed it earlier, and we should leave the design as it stands.
