Let’s Encrypt Begins Supporting IP Address Certificates (linuxiac.com)

Who benefits from this? Even though Let’s Encrypt stresses that most site operators will do fine sticking with ordinary domain certificates, there are still scenarios where a numeric identifier is the only practical choice:

Infrastructure services such as DNS-over-HTTPS (DoH) – where clients may pin a literal IP address for performance or censorship-evasion reasons.
IoT and home-lab devices – think network-attached storage boxes, for example, living behind static WAN addresses.
Ephemeral cloud workloads – short-lived back-end servers that spin up with public IPs faster than DNS records can propagate.

I'm not sure I follow the question. All of the TLD *.arpa is not reserved for private use, only *.home.arpa. So all your internal services are required to be a sub domain.

Sounds like you followed.

Now that I’m moving goalposts, why not use .home.arpa subdomains?

Instead of having to do service.domain.tld it's nice to do service.lan.

Oops. :)
