When a form requires JS to be submitted, there’s a high probably that I abandon that website instead. My expectations of working plain HTML are never higher than with regard to forms. By all means, progressively enhance, but don’t be tempted by the hubris of claiming to know better than the user-agent how the user-agent should work. It’s not just rude, it’s a slippery slope towards systematic incompatibility, weirder bugs than the ones you were afraid of, and security holes.

You say that, but I doubt that in practice. If the form is your bank login or bill pay or anything else you are locked into I really doubt you will give up because of some personal opinion on JavaScript and instead spend the next 30 minutes calling somebody to complete a similar action over the phone.

The goal is to achieve accessibility as equivalently as possible, with as little enhancement as possible, and yet often not force a page change because of form submission.

Calling someone a liar to their face without checking their body of work first just leaves a lot of egg on yours.
