Hi Eric, I have one overall comment and one specific comment on your comments ;-) The overall comment is that we need a starting point to improve HTTP. Sam's draft seems to me at least a stake in the ground from which to work with. I'm all for the document being improved. It would be helpf

Hi, Eric, responding as an individual. Obviously, I disagree with your basic claim that it is too early to write a document like this. I've asked the sponsoring AD to make a consensus call on whether we have sufficient support to be making this sort of statement. If not, then I'll be happy to ta

Ah. I must admit that I find the whole concept of informational documents a heck of a lot less useful, but your reading of 2026 is of course correct. I'll probably still end up treating informational documents as close to ietf consensus statements (but not recommendations) in my head because hone

Part of the problem may be historical: Requirement documents are a relatively recent phenomena and likely postdate 2026. I suspect the original intent of informational documents was to document non-IETF protocols for the benefit of implementors, as well as record various other non-standards
