There are very convenient tools to do https easily these days, e.g. Caddy. You can use it to reverse proxy any http server and it will do the cert stuff for you automatically.
Ofc, but you have to be quite techsavy to know this and to set this up. It's also cumbersome in many low-tech situations. There is certificate revocation, I would really like to see the threat model here. I am not even sure if automation helps or just shifts the threat vector to certificate issuing.
