Overly verbose logging to journalctl

Reproduce the update-manager transaction and compare the duplicated AptKit and org.aptkit entries in journalctl. Trace the logging configuration that produces both entries, and inspect the warning location at /usr/lib/python3/dist-packages/aptkit/progress.py:485. Done means duplicate aptkit messages are removed or controllable without changing logging for unrelated services.

So when I run the update manager, I get this in my journalctl:

Is all this really necessary? For one thing I note that most lines seem to be duplicated, one from org.aptkit and another from either AptKit.Worker or AptKit.Trans. According to AI (which of course could be wrong but if that's the case I'm not sure how I'd go about finding the right answer), the only way to control all this logging to journalctl would be to add a LogLevelMax=error to the org.freedesktop.PolicyKit1 service, which would suppress INFO and WARNING messages for a whole lot of services, not just aptkit. So unless you guys can tone this down somehow or add a configuration option to control it, there's no way a user can control this level of verbosity.

If at least the duplication could be removed, that would help a lot. Preferably removing the ones from org.AptKit as those come up yellow in journalctl even when they are INFO level, the AptKit.Worker/Trans obey normal coloring conventions. Thanks for any help.
