Ick.

We went through this before multiple times. One notable was the impact
of chunking and muxing in HTTP, effectively reinventing IP inside.

"A person with one watch always knows what time it is. A person with two
is never sure."

I can't imagine what combined congestion control of TCP would mean
inside the network - we had a hard enough time defining it for either
TCB sharing or the Congestion Manager just at the endpoints.
