You can! And then if you want to establish causality from log to log, representing which part of a system calls which other part, you can add another id that lets you know which log is a “parent” of another. And maybe later, you may need to propagate metadata across a request, so you build that system and use it to better enrich your logs. And maybe later, you’ll need to correlate subsets of logs with other subsets of logs, so you build a way to “link” related sets of logs together. And so on, and so on. All of this is possible with “just logs” today and if it’s your jam, go for it. But these are reasons why tracing libraries exist.
