and they will replace it with * and just do it every day just in case

Running an update script every day is good. Certbot defaults to running twice a day. Just use something with similar logic, waiting to renew short-lived certificates until halfway through their validity period. That way the actual load is nice and spread out. And you should get that logic by default if you do a normal setup.

I’d expect most will do this. I wouldn’t be surprised if LE expects this.
