Custom domains would be huge for me, but I totally understand. How would they ever manage to do it? They'd either need a zillion separate entries, or the broadest wildcard cert ever.

Lots of certificates with 100 hostnames each is how CloudFlare does it.
Let's Encrypt?
Separate entries in what? Computers do pretty good at handling many "entries". TLS will indicate the host so they can send the right cert back.
Sorry, I meant in an Apache config file or something.
Or they could let users specify their own certs.
Wordpress did this by issuing Let's Encrypt certs on demand for every domain people CNAME their way.
