Yeah... or...... maybe they should just build websites the proper way the first time around, returning plain HTML, perhaps with some JS extras. Any user-entered input needs to be validated again on the backend anyway, so client-side JS is often a waste.

This falls apart the moment you need to add rows to a table or show and hide things in response to values selected in a dropdown. Even the lightest JS app centered around a big form is going to become a huge pain in the ass for literally no benefit. In a company of 100 people, that <0.5% of people who disable JS could literally be one guy, or no one at all.
