I can think of another example of a package restarting a service:

The glibc and glibc-common packages run a command called
/usr/sbin/glibc_post_upgrade.x86_64 or
/usr/sbin/glibc_post_upgrade.i686 (depending on whether its an x86_64
or i686 package) in their RPM postinstall scriptlet.

It runs service sshd condrestart if it detects that
/etc/rc.d/init.d/sshd exists (so, nothing on systemd-based systems).
It also runs 'telinit u' too.
