At my work, all services have a "debug" HTTP port with endpoints to, among other things, dump the running configuration. But I'll admit that's less general than flags, since it depends on the server processes being built from our standard frameworks. Also for us, we can't SSH onto hosts, and the scheduler that actually knows about args/pids/etc is fairly deep behind the curtain, but HTTP access is easy. But you could see different companies having different constraints.
