An HTTP/2 client is pretty easy to implement. Built-in framing automatically improves a lot of complexity, and if you don't need multiple streams, you can simplify the overall state machine.

Perhaps something like "HTTP/2-Lite" profile is in order? A minimal profile with just 1 connection, no compression, and so on.

Isn't the original post about servers? A minimal client doesn't help with server security.

I would endorse your idea, though, speaking more broadly! That does sound useful.
