Doubt it. I suspect that browsers have some sort of happy eyeballs algorithm for determining whether to use http/3 specifically because some networks don't handle it well. In those cases it'll fall back to http 1.1.
>Now all those traffic shaping middle-boxes are worthless
How so? how is TCP 80/443 and UDP 80/443 harder to traffic shape than TCP 80/443 alone?

That's more encryption (ie. https) than switching to http/3. Also, encryption is already mandatory for http/2 (for most browsers).
