You are much less likely to sit at the keyboard for 16 seconds than for
3. When stealth font-lock kicks in, and you press a key, it doesn't
react (by stopping fontification) until it finishes processing the
current chunk. Thus, if it begins fontification too early, you will see
annoying delays in responses to keystrokes. You might not mind those
delays if you are really taking a break from typing, but you _would_ mind
if you just stopped for a few seconds to reread the text you've just
typed.

Would you object to changing the defaults as the first approximation, and
adding the more sophisticated operation as the second one?
