We are fully committed to end-user privacy. As a result, Quad9 is intentionally designed to be incapable of capturing end-users' PII. Our privacy policy is clear that queries are never associated with individual persons or IP addresses, and this policy is embedded in the technical (in)capabilities of our systems.
It is about the hostnames themselves like: git.nationalpolice.se but I understand that there is not much choice if you want to keep the service free to use so this is fair
Is that really a concern for most people? Trying to keep hostnames secret is a losing battle anyways these days.
You should probably be using a trusted TLS certificate for your git hosting. And that means the host name will end up in certificate transparency logs which are even easier to scrape than DNS queries.
