I'm not convinced this is the case, though. If you have some bad (or at
least selfish) actor that is already shoving data into headers to avoid
flow control, then I would imagine this situation would make them want to
shove even MORE data into headers, since it's still not flow-controlled,
but harms their data. What's the "best" way around that for one of those
actors? Put it ALL in headers. Perhaps I'm just more pessimistic than you
are, though :)

Note, I am (like you) definitely not suggesting (or trying to re-open) the
flow controlled headers argument. I was already against flow controlled
headers. I just think that this provides the worst of both worlds.
