You’re no more involved than sudo apt-get update && sudo apt-get upgrade -y in that you’re sitting watching mostly useless info output to your screen while you wait.
It’s essentially just a way of saying “the update is still happening and this is about how far we are in the process” so you’re not just twirling your thumbs at a black screen or nothing but spinning dots.
User feedback is pretty important, be it verbose output of what’s currently happening, or just a progress summary in the form of a total percent complete.
