I am a bit unsure why some log statements are set to debug and others to info, and if this should be modified or just left as is?

I am a bit unsure why some log statements are set to debug and others to info, and if this should be modified or just left as is?

I think in general we should either change the levels or the logging, so my take on this is to leave levels as-is for now.
We could open an issue regarding the levels though, if you want to follow up on that. Or discuss this during an appropriate meeting.
