Note related bug if a package were to use debhelper-compat 10 vs 9 on focal.
In Focal, debhelper-compat 10 will incorrectly introduce ignore the params
dh_systemd_start --no-restart-on-upgrade --no-start
And will still inject which will restart all services across package upgrade with something like the following pseudo script:
deb-systemd-invoke try-restart <all services>
Moral of the story, don't shift your debian/compat version on stable releases or bad things could happen.
