They would need some incentives to make it work in big orgs that have MITM and/or restrictive firewalls.

HTTP isn't the only L7 protocol.

"Betteridge's law of headlines" applies, I suspect...

We're having difficulty getting IPv6 up and going, and that's 100% supported by everyone.

QUIC has a substantial CPU overhead, due to lack of hardware or kernel acceleration.

QUIC deployed worldwide might cost us a power station or two...

Ideally those incentives would be combined with disincentives for those organizations to continue breaking the web. A combination of the two seems more likely to be successful than either alone.

this.

Many people here seem to not realize that TCP is used for much more then just http/https.

Quick might be nice for web traffic, but i see little reason to use it as an underlay for BGP for instance.

tcp != the web.

Also, most firewall don't break TCP, they break HTTP(S) because they want levels of control.

I wasn't referring to TCP, and the web isn't purely TCP. UDP and ICMP are important, and some firewalls just block them completely.
