I don't think it will be true of HTTP/2 either, at least not uniformly.
The nature of proxies is such that they usually optimize for local network
constraints rather than what would be "normal" for the global Internet.
We usually don't care because most proxies are inside corporate intranets.

The public Internet proxies tend to be privacy proxies, which might
do very strange things with their connections just to provide
sufficient incoming traffic to mask where the outgoing traffic came from.
