The earlier statement about why this would not work (corporations getting MITM certificates from bad actors in the root pile) doesn't actually apply because the client will have a single TLS trust anchor, possibly even one not even in the root pile.

Why would the client even need a single trust anchor for this?

Current unbound dns-over-tls completely ignores the TLS. It is only used
to get out, not for any type of authentication of transport or data.
