Your comment on OPTIONS is valid, but we should also consider protocol
upgrades. Maybe the test should be if the method is OPTIONS and the
request contains an Upgrade header field.

Regarding optional upgrades, what happens if the backend responds with 101?

As the VIP says, no matter how pipe turns out in v5, but how does H2
deal with protocol upgrades? I think it doesn't (eg. websockets)
