No, it makes the buffer display "instantly" instead of taking a few
seconds to highlight it from head to toe.

Just the "one screenful" at a time, so still "instantly".
IOW, it makes it work like "jit" intends.

I don't know what you mean by that. I use `outline-minor-mode` because
I like the way it gives me an overview of the whole buffer (akin to an
"in-buffer speedbar"), not because of its interaction with
jit/font-lock performance.
