I think that is the problematic point with Caddy right now - if you are using it, you are actually a beta tester. This is a problem for sites with lots of traffic because things start to be different with servers maxed out - Nginx is battle hardened, learned it´s lessons and you can be sure that it works under extreme load as expected. Also you definitely need rate limiting out of the box, not as some beta plugin that needs to be fiddled in manually. Also streaming is something that needs really good testing with high loads. K8s is important for many people, too. Of course it is not easy to find someone willing to test on a high traffic site when there are well established alternatives since many years and no actual problem needs to be solved. "Easy configuration" is not very important for admins of high traffic sites. Not easy to find what could be the selling point for Caddy, but it should deliver one or two special things more.
