The specific use case I had in mind is that of an endpoint sending small and frequent application data units to the same peer - e.g., sensor readings through CoAP observe. In this (and similar) situation(s) where the payload / header ratio is low one wants to have as little transport overhead as possible. Now, it turns out in the specific situation (and whenever the data framing is provided by a higher layer protocol - CoAP, SCTP, DNS) one might as well buffer and coalesce all the application stuff into one single record, making the need for CID compression moot. So, I am now convinced I don't have a compelling case to bring to the table and might as well move into Martin's "vanishingly small use cases" camp, therefore subscribing the gist of PR#148. PS A note about the more general argument of a pure pseudo-header approach: it'd enable compression boxes at ingress into a constrained network, which would be really useful. Without a thorough analysis wrt header malleability this is unfortunately out of reach. -- IMPORTANT NOTICE: The contents of this email and any attachments are confidential and may also be privileged.
