Stealth fontification is not supposed to be unobservable.  Instead it's
supposed to make less observable the fact that fontification is done lazily.

So to observe that stealth fontification provides you with some benefit, you
have to turn it off and see if jit-lock behaves worse.

We know fairly well about the downsides and we know they don't affect
everybody all the time, so this is not the interesting part of
the discussion.
