I think the branding as a "repair" is meant to mislead uninformed users but I am totally with you, I would LOVE to get a list of settings that are going to change after an update so I can approve them. I can't tell you how many times a random update reverts something I set up ages ago when I installed windows. Most of the time I may not notice the setting change for a while, until one day a feature doesn't work as I expect it to.
