This is a terrible implementation of domain verification. dns-01 and http-01 are more or less standardized at this point. Use them, and don't roll your own. Reference: https://letsencrypt.org/docs/challenge-types/.

They definitely should have used HTTP-01 if they’re doing verification on the web, but since this is about using a domain as identity this really belongs in DNS.

The issue with DNS-01 (and HTTP-01 to a lesser extent) as someone else mentioned is that the user friction is really high.

I’ve been working on a solution to this that I’ve been meaning to post to HN and this seems like as good an opportunity as any so here it is: [1]

It’s a method of storing a hashed (and optionally salted) verifiable identifier (think email or mobile) at a subdomain to prove authority for a domain.
