If you grow a window, and the sender sends the delta at 100G, and
receiver is 10G, eventually you'll hit that 10G port at 100G rate.
It's largely an edge problem, not a core problem.

Quite, unfortunately, the problem I have exists in the Internet, the
problem you're solving exists in Ohtanet, Ohtanet is much more
civilized and allows for elegant solutions. The Internet just has a
different shade of bad solution to pick from.
