I only wish I were insane; but from where I'm sitting, QUIC has broken my internet, and the resolution is blocking QUIC.
The QUIC protocol itself isn't breaking anything ; some middlebox is breaking QUIC. It's likely collateral damage from honest attempts to mitigate bad stuff. Blocking QUIC at your home edge surely helps to some degree, but the upstream issue still remains.
I recall reading a draft from the WG about having things open a parallel TCP connection in case UDP got horked for seamless fallback, but I don't remember if it ever moved past that, or if anyone actually implemented it.
UDP is broken
The Google devs said it would in fine in 2014
They said it would be “exciting”
UDP is not "broken". UDP is the UNRELIABLE DATAGRAM PROTOCOL and it is living up to its name! What is broken is something pretending that the "U" in UDP means something other than UNRELIABLE and then pretending their use of an unreliable delivery mechanism makes it reliable when that clearly is not the case. In other words, applying a coat of paint to a sows ear to make it look like a silk purse does not make the sows ear into a silk purse. It is still just a sows ear painted to look like a silk purse, and still behaves like a sows ear. -- The fact that there's a Highway to Hell but only a Stairway to Heaven says a lot about anticipated traffic volume.
