Some notes about HTTP/3
Robert Graham from ErrataSec on QUIC aka HTTP/3:

'Google (pbuh) has both the most popular web browser (Chrome) and the two most popular websites (#1 Google.com #2 Youtube.com). Therefore, they are in control of future web protocol development.'

Faster connection setup and latency; better bandwidth negotiation when using multiplexing; user-mode stacks by building on UDP and using recvmmsg(); and better mobile support for roaming IPs.

HTTP-over-QUIC to be renamed HTTP/3

Internet protocols are changing
per @mnot. HTTP/2; TLS 1.3; QUIC and UDP; and DOH (DNS over HTTP!)

The hidden cost of QUIC and TOU
The recent movement to get all traffic encrypted has of course been great for the Internet. But the use of encryption in these protocols is different than in TLS. In TLS, the goal was to ensure the privacy and integrity of the payload. It's almost axiomatic that third parties should not be able to read or modify the web page you're loading over HTTPS. QUIC and TOU go further. They encrypt the control information, not just the payload. This provides no meaningful privacy or security benefits.

Instead the apparent goal is to break the back of middleboxes [0]. The idea is that TCP can't evolve due to middleboxes and is pretty much fully ossified. They interfere with connections in all kinds of ways, like stripping away unknown TCP options or dropping packets with unknown TCP options or with specific rare TCP flags set. The possibilities for breakage are endless, and any protocol extensions have to jump through a lot of hoops to try to minimize the damage.
