I think that this is the correct thing to do.

At the very least, I'd assume that server-driven prioritization using content-type would work well to some extent. Since the early days of H2, we've doing that for browsers that does not use dependency, and it is my understanding that it has been working OK. Though it would be preferable to have the capability of servers and clients providing "hints", especially to distinguish between a render-blocking JavaScript file and a asynchronously-loaded one.

I'd assume that once the QUIC and HTTP working group agree to drop priorities from H3, it would become the task of the HTTP WG to determine what to do.
