The EV certs still exists, but the browsers don't really differenciate between DV and EV certs anymore.
But TLS certificates solve a much narrower problem than WEI ("are you communicating with the site you think you are") and are widely and cheaply available from multiple organizationally independent certificate authorities.
In particular, TLS certificates don't try to make an assertion about the website visited, i.e. "this site is operated by honest people, not scammers". WEI does, with the assertion being something like "this browser will not allow injecting scripts or blocking elements".
