>okay so clearly you don't know what you're talking about because they do use existing standards/DNS as the primary way to validate domain ownership.

I'm not going to speak for the commenter you're replying to, but I don't think anyone here is talking about the standards-compliant, DNS-based domain verification system. I think we're all talking about the non-standards-compliant, /xrpc/-path verification.
