I understand the attractiveness of the idea but I think we're too late in the process to seriously consider changing this, independent of the specific details of proposals. How should a server that has no intention of enabling this setting respond to HEADERS that include other instructions? If the answer is to blow up the connection then the (unintended?) side effect will encourage clients to start connections by sending all requests as "Literal Header Field Without Name Reference" until they receive the setting. But that stage of a HTTP/3 connection is the exact place where static and huffman have the most value; we groomed the static table to suit best the first flights of client requests. My concern is that by trying to accommodate some smaller segment of HTTP clients, we cause a serious regression compared to HTTP/2. This sort of thing seems better suited to a version that is "profile of HTTP/3" that disables some things and mandates others. -- You are receiving this because you are subscribed to this thread.
