Wouldn't auto-instrumentation be more useful and flexible for everyone? The hardcoded instrumentation seems rather overkill for most use cases.

Never really thought of auto instrumentation. If someone is hosting in containers though it'll make it hard to do, so having this option at least gives the Hoster a way to get decent metrics etc.

I plan to try and add some tracing and better metrics so this is just a start
