Updating a shared library requires an understanding of which services (and interactive programs) use that shared library. There’s a lot of room for mistakes. So while restarting specific services can be worth it for a high-availability server, for a desktop PC I find it easier and less error-prone to just restart the machine.
Outside of the kennel a reboot is not necessary you just restart the app/service it’s really not rocket science.
