The other problem with the experiment was that WebSockets was the basis. If the UPGRADE header is removed for any reason (compliant or not) then the WS connection fails.  In HTTP/2, most of the cases where UPGRADE is removed, it will simply result in a HTTP 1.1 connection.  That itself makes the "failure" much different.

Thanks!!

It would be interesting to repeat that experiment. It's now 4.5 years later, and deploying Websockets may have caused broken code to be fixed.
