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.
