Yes, you’re right that 9012 is another possible ref. Regarding the option of doing it in the current spec —
- I hear you that you’re not certain you’d be capturing every relevant reference, however I think this is a case of “best is the enemy of good”. Listing the known references would be an improvement over the current state of affairs, likewise updating the description. - There is nothing preventing a later doc from updating the registry again, if that’s deemed necessary. Registries are updated all the time. So, we wouldn’t be foreclosing any options or doing anything irreversible. - Getting WG input (such as would come from a full last call) is certainly important for many things, but you’ve just pointed out yourself that this isn’t a functional change, so I think it’s unlikely that any harm would ensue from not invoking maximum process. I had a look at BCP 26/RFC 8216 and this approach seems consistent with the guidance there. Indeed, strictly speaking it would be inappropriate NOT to add [this document] as a reference in the registry, at minimum — so the only question then becomes, whether to update the description and add the other references at the same time. Bottom line, I continue to think it’s appropriate to do it in the current spec, and more expedient. Seems like all upside, no downside, very good bang-for-the-buck. Here’s what (per my reading of BCP 26 §7) the bare-bones update would look like: 9.X Subsequent Address Family Identifiers (SAFI) Parameters Registry IANA is requested to add this document as a reference for value 128 in the Subsequent Address Family Identifiers (SAFI) Parameters registry. That would then leave the other work for a later draft, as you suggest. I’m only providing the above for clarity, it’s not my recommendation, the earlier version is. —John > On Mar 22, 2022, at 3:27 PM, Ketan Talaulikar <ketant.i...@gmail.com> wrote: > > > Hi John, > > This point was discussed amongst some of the authors.
