I had no discussion yet about an SRU, and I share this concern. The biggest issue I think is the maintainer script, which even without our changes (pristine debian) is already forcing a bunch of chown/chmod everytime. Even if an admin changed config files, the maintainer script would still be running chmod/chown on /var/log/tomcat9. I don't really know how someone would have adapted and fixed their system in the meantime, unless they changed the logging directory to be somewhere else entirely. Then all the remaining changes are in config files, which a package upgrade wouldn't override.

I could refrain from my chown in postinst if I detect something changed, but then I would have to include debian's chown/chmod in that if/then/else clause.
