> Don't act like every form is 5 simple text inputs.

Well to be honest 99% of forms are 5 simple text inputs with a select. What was the last time you had to implement a "choose up to 5 locations in the radius of 10km", really?

> What about form fields like "pick a point on a map"?

Same thing: of course there are rich forms for which you need JS, but they are the exception, not the rule.
