I have not. It is quite the niche problem. Mostly because web performance is so bad across the board that saving a few milliseconds just isn't meaningful when your page load takes more than a second and mostly is stuck in javascript anyway. Plus everybody just uses cloudflare and having that CDN layer use whatever modern tech is best is very much good enough.
Sure, but there's video streaming, server to server long polling bidirectional channels, IOT sensors and all sorts of other things you probably use every day that can really benefit from HTTP3/quic.
