Earlier versions of Caddy were just a single binary that accepted signals to reload; the newer versions add a bunch of process management stuff that just got in the way of our existing tooling (...why remove the signals? ugh!) so we just switched back to Nginx.

The only signal we don't support anymore is USR1. (It's not a powerful-enough API for config reloads.) That was why you switched your entire web server stack?
