Here, it isn’t open source.

It doesn’t make a lot of sense for LetsEncrypt to spend time adding support for such certs, since both a domain name and a cert from another CA are cheaper than buying an IPv4 block

certificates can only be obtained for domain names

That is not true, nothing prevents it on the technical side, and even some trusted CAs sell them under certain conditions

The check $LEMMY_HOSTNAME == http* will give a false positive if (for whatever reason) the domain name starts with http
