Doing so does not necessarily mean that HTTP/3 will ship without a priority scheme. The expectation is that work will continue (in the HTTP WG) to develop a new priority scheme that is suitable for HTTP/3 (and ideally, available as an extension to HTTP/2).

If HTTP is ready to ship, but a new priority scheme is not agreed to, both this WG and the QUIC WG will have to determine a path forward at that time.
