There is one CA (forgot the name) that provides EV certs (for websites not code signing) that looks up data in national registries, they have a lot of stuff automated so it's quick and relatively cheap. So in theory it's possible for code signing. But Let's Encrypt repeatedly refuse working on code signing certs (it's not that cheap to operate as website DV).
