But websites that don't bother to make their websites accessible without JavaScript have a bad track record for implementing ARIA (correctly). Good accessible design has benefits for everyone, not only the disabled. For instance, that half of the web breaks when you turn off JavaScript, turned into a security issue when Tor Browser enabled it by default (to not confuse their users with a broken web). Progressive enhancement and accessibility go hand-in-hand. If not for accessibility reasons, then develop websites with accessible JavaScript for security, SEO/automated access, or progressive enhancement reasons.
