It's kinda yo-yo effect. Some devs are more aware of accessibility, even AI agents help sometimes, but on the other end lots of devs don't want to learn and use semantic HTML, and I as accessibility specialist often see absolute nightmares like seven spans inside a div, inside a heading, inside a button, inside a link, all of this inside eight layers of divs and spans — I almost don't exaggerate. for instance, in one of my last audits I saw a clickable div realized as link, inside it lots of stuff, including headings, images, buttons, lists and what not, which is absolutely against all standards, from HTML to WCAG. Anyway, it's varied, I'd say.
