I can't help to imagine the scenario where a costumer has a problem and "we" ask for the logs and there's a bunch of holes and we can't diagnose the problem...
im new around here and in other projects I've participated I've seen a lot more logging... ultimately speaking, instrumentation can be cover by other tools such as datadog, but I've browsed some files and it's quite easy to find entire classes that doesn't log anything...
I don't have an actual need, I just want to know more on how you guys tackle this so I can contribute accordantly and if you, project leaders, feel that we need more logs, I could comply... but if you are happy with the current setting, ok!
