Thanks for tracking this down! There shouldn't be any problem to
improve this for 5.3.0 --

Logging for the Java (e.g. Blitz) and Python (e.g. Processor) servers
is handled separately, but both are configurable. See
https://www.openmicroscopy.org/site/support/omero5.2/developers/logging.html#java-servers
for more information.
