> Is lynx up to spec on HTML5 ARIA attributes? My understanding is that that's how accessibility is "supposed" to be done now

No, that's not true at all and is unfortunately a common anti-pattern. Accessibility is supposed to be done by using standard HTML elements and attributes. ARIA is there to extend / fill in the blanks and to fix things when people deviate from the norm. For instance, if you have a button, you should almost always use the standard HTML <button> and only use some other element type with an ARIA role=button if it's unavoidable. And <button role=button> is redundant. Best practice is still to use the semantics defined by HTML, as it always was.
