Maybe you live in some Magical Christmasland where they do, but in my experience in healthcare, education, project engineering, and the public sector this absolutely never happens. You have a third party application, you can be sure that they don't configure it to use these hooks or the built-in package manager or document their dependencies or anything like that. except the applications the server was actually set up to run. In my experience that works great with everything. Rocky/RHEL has a needs-restarting command in yum-utils. Debian's package-hooks contain daemon restart provisions.
