That it would be easier to experiment with new prioritization schemes in HTTP/3, due mainly to the removal of priority information from the H3 HEADERS frame. This makes it quite feasible to write an extension along the lines of "the extension replaces/supersedes the base standard PRIORITY frame when negotiated". In contrast, a H2 extension either needs to define a new HEADERS format or provide supplemental information in the form of a new frame, which is possible but a bit redundant. There didn't seem to be much appetite for adopting H3 priority placeholder design in H2 (I cant remember when this was presented, sorry). I'd be curious to know if there is more interest in other alternate priority schemes in H2. Lucas >
