This was always a concerning eventuality to me... There are numerous technical security-related caveats that make me worry about HTTP/3, and I have past trauma regarding the lossy mess that is UDP. That's my own opinion, though.
The real question is, will it ever actually become necessary? Are there any webserver projects or websites that actively only support HTTP/3? Or even any that only support 2? Or 1.1?
