At last a sane person. Logs are for identifying the event timeline, not to acquire the whole reqs/resp data. Putting every detail into the logs is -in my experience - makes undertanding issues harder. Logs tell a story. When, what happened, not how or why that happened. Why is in the code, how is in the combination of, data, logs, events, code.

And loosely related, I also dislike log interfaces like elk stack. They make following track of events really hard. Most of the time you do not know what you are loooking for, just a vauge understanding of why you are looking into the logs. So a line passed 3 micro seconds ago maybe your euraka moment, where no search could identify , just intuition and following logs diligently can.
