I can't speak for most middle boxes, but at least nginx does have pretty good http2 support. I believe that is pretty common.
The main issue I see with middle boxes is not supporting TLS ALPN (which HTTP/2 depends on). This is common in packet inspecting firewalls, which lag in functionality. That said, Google is gainfully using gRPC in some flagship Android applications, so it definitely has some experience in exotic environments.
