I'm not sure what that would solve. You would still need some central entity to sign the DNS TXT record, to ensure that the HTTPS client does not use a tampered DNS TXT record.

If someone can tamper with your DNS TXT records now they can get a certificate for your domain.

Not tamper with the record directly, but MitM it on the way to a target.

That's already the case with dns-01 verification, no?

Besides, if someone has access to your TXT records then chances are they can also change A records, and you've lost already.
