I don't see how that could work.   I agree that it's a problem in need of a solution, but since home.arpa wouldn't be externally visible, you couldn't use the fact that you can publish in a name in it to do the ACME authentication.

I was hoping to get IP-based certs, but it turns out that letsencrypt (probably wisely) doesn't offer them.
