I did this

curl -s --trace - --trace-config http/2 https://caddyserver.com

== Info: [HTTP/2] [0] <- FRAME[SETTINGS, len=30]
== Info: [HTTP/2] [0] MAX_CONCURRENT_STREAMS: 250
== Info: [HTTP/2] [0] ENABLE_PUSH: TRUE
== Info: [HTTP/2] [0] notify MAX_CONCURRENT_STREAMS: 250

I expected the following

curl should log all known settings parameters and their values. This is crucial to simplify debugging cases like caddyserver/caddy#6567 (comment) where the presence of ENABLE_CONNECT_PROTOCOL changes how websockets are bootstrapped.
