My point is that regular domain validated CA
should be the sole job of registrars. It would even prevent parallel certs being fraudulently issued - a domain can only be registered at one registrar at one time.
Sure, you could have the other CAs still offer EV (real-world identity) validation as a value-add.
But it's pretty silly that, currently, you have to pay a third party (today's CAs) to validate something that the registrar already knows for sure.
