No, something like that is fine. I am just trying to convey that there is a huge industry around fixing these problems very incrementally. ohdear.app today, then DataDog... all because they can't just run Prometheus and Alertmanager.
This isn't how I like it, but I totally see the use case. Caddy is a part of that use case and is probably the reason it exists. I think that's fine!
(Edit: ohdear is really neat though, I think people might want that no matter what. You have to serve your status page from somewhere, might as well get some cert checks thrown in for free!)
