Should disabled form elements be accessible?

If a form element is disabled does it need to be accessible? If so, how?

[dakahn]

In short, yes. A disabled form element should always have the disabled attribute and must not have aria-hidden or display: none so that screen readers can inform the user

If the form element's disabled state is meant to communicate and prompt action from the user you must have some other accessibility affordance. Our provided invalidText prop used on the preceding form step/element would work nicely

The user could then infer that the next form element is disabled because they have an unfulfilled requirement on the previous step.
