Sure, map viewing definitely doesn't need JavaScript, but Google Maps definitely does. I don't see how you could reasonably implement something like Google street view without JavaScript. Even just having the different locations on the map fade in and out of view as you zoom requires JavaScript, as far as I know. Personally, I don't want to have to use a stripped down version of maps, I want to be able to go into street view and see the locations, and smoothly see more detail as I zoom in.

Perhaps a better example is video calling. Definitely can't do that without JavaScript. My point is that disabling JavaScript entirely eliminates several classes of websites. I think it is better to have reasonable limits to JavaScript than make these types of websites impossible.
