The purpose is to simplify logfile analysis: it's saying "hey logfile
analyzer, you can stop remembering the history of this queue ID."

Never? That would be most likely lost logging due to systemd or
rsyslog rate limits, or naive logfile analysis that misses that
that the logfile is rotated, so that the 'deleted' record is written
to different file than the one you're looking at.
