To answer @marten-seemann 's first point, I do think that the congestion control rules in the spec matter, even though they're unenforceable. Implementers will sometimes do whatever the spec lets them get away with. The reason I brought it up was the fairly stupid "never send an ACK with data" loophole.

Regardless, this is clearly DOA and I'm closing it.
