I do know there is a special tag for systemd-journald, but I believe it to be special case of logging, synonym of logs.
My issue being in the definition of logs (emphasis mine):
Configuring or analysing log files (text files where programs output error and informational messages, useful for debugging and troubleshooting).
journald actualy saves data in binary form so my question is whether we should ignore this difference, don't use the logs tag with journald questions or somehow change the tag.
