That can become very dangerous.
If there is a single limit on framesize, then it would end up being large
because the receiving party is unlikely to know how large the headers
should be, and must set it to as large as they ever believe headers might
That negatively impacts reactivity.

One could fix this by have separate headers vs data max frame size.
Then we'd need to figure out which one mapped to SETTINGS and other control
Would it be a control-frame vs data-frame setting?
