You're probably right, this is a issue that isn't unique to Arch. In this case, I would have been fine if a default had been chosen for people who didn't do the reading. Something like installing a plugin that will keep basic functionally of the app working.
I agree that reviewing terminal output is a valuable skill. I'm often lacking the attention or energy to pay attention to every update. I wish that wasn't the case because I believe I have higher than average emotional reactions when things go unexpectedly but the lack of attention -> unexpected event -> emotional reaction loop is a pattern of my life I've come to accept.
