I happened on the "restart" by chance one day when looking at the various Workspaces.
I believe they can offer users a variety of icon sets to use in the program, but the original icons are still the best in my opinion. Maybe the other icons look good on 60" monitors, but they ain't making it on my 24's. I can sit for for 30+ seconds (or longer) trying to figure out what tool the icon is attempting to represent and should I click on it or another one. After a few of those, it's back to the original icons.
