HTTP/3 Prioritization Proposal

I'm happy to draft it as an I-D but wanted to see if people thought there
was merit to it before going through the effort:
https://github.com/pmeenan/http3-prioritization-proposal/blob/master/README.md

Basically, I'd like to propose replacing the dependency trees and weights
with a simpler scheme that has "priority" and "concurrency" values for each
stream (with no shared tree state).

There may be HTTP use cases that it doesn't cover but coming from the
browser side of things (and having spent some time working on server-side
prioritization) it should make it MUCH easier to manage prioritization and
to schedule an "optimal" prioritization for resources.

Thanks,
