Sure. This is a minor detail that can be customizeable, for example.

Nope. 0.2 sec is the delay that is barely noticeable. When "slow"
mode-line packages affect users it is usually much worse than 5fps.
(Though sometimes it is due to redisplay being fired frequently, not the
individual refresh times being too large).
