Do you print to /dev/stdlog using the correct syslog format or use journald and its format?

Because if it's not one of those, the "levels" are useless.

No, the levels are not useless, far from it. Even if you just print to stdout, prefixing each line with a (maybe colored?) level info is very useful. Also, if later you decide to use xyz format, it is trivial to implement this. Changing all logging calls? Not so much.

Just use a real logging daemon and it will be the colours by itself.

It will also let you query for which level you want.

Uh? Make a good library using the same interface.

To answer your question, the levels are important for both regular usage and debugging when something goes wrong. I create a number of debug/info/warning/error log messages throughout the tool and allow the desired level of logging to be set as a CLI argument - or even run in silent mode if desired.
