Getting rid of `if ($host != $server_name) {`

[MarcelWaldvogel]

    # Prevent Nginx from leaking other server configurations on the same machine
    if ($host != $server_name) {
        return 444;
    }

All configuration files contain this block. nginx documentation recommends to avoid if blocks whenever possible, because if is evil.

I guess the same functionality could also be achieved by creating a server block which is included before any of the conf.d/* files. What do you think?

Yes, this can be removed now as later I implemented this block.

(And the self-signed certs are for this block)

I deleted this block. Closing this issue and will come in the next release.
