What's the problem 🤔

When using the DOT functionality, should I be concerned if the logs say [dns] using plaintext DNS at address 1.1.1.1? I guess I'd expect it to say "using TLS DNS" or similar? Is this just a misleading log statement, or is it failing to use DNS over TLS and falling back to plaintext?
