> It seemed to me that Http2 was meant to be a file transfer protocol, but designed by people who don't really quite understand how TCP performs in the real world (especially on mobile)

And not only mobile, same applies for server-server connections over near perfect, inter-dc connections.

Even gigabit, and above links drop packets... because it's how TCP is supposed to work!

The higher is the speed, the more aggressive curve will be used by the congestion control algorithm.

In other words it will hit drops fast, be in the drop zone for longer, and this will be recurring more frequently than on slower links.

In fact, faster congestion protocols for speeds above 500 mbps get their speed by having A LOT MORE drops, not less.

Any protocol designed for the TCP transport must have been designed to work in concert TCP mechanics, not fight, or try to workaround it.

This is a perfect example of how AB test vodoo lead people down the rabbit hole.
