At this pace and having adopted CI/CD methodology, we may QUICkly run out of UDP ports to use.

I’d actually switch to ICMP. Type 8 code 0 and Type 0, code 0. Then staging a war on rate-limiters around the world.

Also, 123/udp seems to look interesting ;)

Now… once we are aware, the only question is — where we go from here?

Well, it's clear the UDP 443 experiment wasn't entirely successful.

So clearly, it's time to use the one UDP port that is allowed through at the top of everyone's ACL rules, and update 
QUIC in the next iteration to use UDP/53.

*THAT* should solve the whole problem, once and for all.
