I think the confusing part comes from the ENABLE word in the setting name. We could proceed differently by exchanging a supported model for priorities : SETTINGS_HTTP2_PRIORITY_MODEL It could then take the following values : 0 (default) : as specified in RFC7540 1 : priorities not sent and silently ignored 2 and above : to be documented in future specifications This way it seems more natural to consider that unless advertised, we stay on RFC7540 and nothing changes.
