Well, HTTP/3 the specification lack priorities in any form whatsoever :)

But yes, you're totally right that an HTTP/3 endpoint implementation can do prioritization based on locally available information. What is lacking is a way for and endpoint to provide information to the peer to facilitate the prioritization.

I'll be interested to see what sort of normative language we end up with for how an endpoint is required (or not) to act on this information.
