That horse left the barn at least a decade ago, before SPF, DKIM, DMARC, and a lot of other TXT records primarily intended to be consumed by computers. Humans can read them, but this human can't do much with records like this: taugh.com. IN TXT "google-site-verification=7SCAvuZtE7dOCpG0drHDEBOqco9JnPzFUIUBSgU3eWc" Whether to use a TXT record is of course a subsidiary question to whether DNS SNI indirection is a good idea in the first place.
