Well, first I have to say that I'm not in the snow a lot these days. But I've spent extended winter time in Nebraska, Japan, Rhode Island, and a little bit in Utah & the Sierras.
The first thing I would observe is that the need for this "wipers up" deal would vary largely depending on what kind of winter precipitation you get in your area. I can tell you that if you get a lot of "wet" snow &/or freezing rain, it can be a pain to break those wipers loose from the windshield after a serious storm. Whereas in some other areas, you could get a foot or more of dry snow & really not have a problem with wipers freezing to windshield.
Soooo, if you need to to this, you probably know already. If you don't, then of course you wouldn't bother. But it's very much different in different areas.
