Please, tell me more about how I know nothing about anything outside
Firefox. We've always been looking for hard, technical arguments in these
discussions, so I made one. I'm still waiting for one of yours.

And for those kind of applications, they are more than welcome to make a
convention in their implementation that they never send more than 256.
Saying the minimum max frame size is 4k is not the same as saying you must
send 4k in every frame.

 But we shouldn't make it quite so easy for them to shoot themselves in the

And with that, I'm done talking about the "internet of things", which is
such a vague statement that encompasses such varying capabilities in
endpoints that it's honestly meaningless to talk about in any real sense.
