I'd take wide shoulders over sidewalks any day. Wide shoulders increase safety for many more people. People on bikes can use them. Pedestrians can walk on them. People pushing strollers can use them. You can change a tire on them. Drivers can use them to navigate obstructions (like people who cannot promptly take a left turn). Drivers can pull over and re-tie down a tarp that's too loose or change a tire. Snow plows can easily clean them. They're cheaper (than dedicated sidewalks) to build and maintain and don't need curb cuts.
Using banked curbs everywhere is another more useful alternative to normal sidewalks (less useful to some pedestrians but create a larger perceived separation from traffic than a shoulder and impossible to kill a tire while parallel parking)
Edit: At least offer up a counter opinion if you're gonna down-vote.
