I would think the average user visits Facebook through the Facebook app, not through Safari, so that should very much affect them. Google is a different story..

  Not on desktop, however. Safari for macOS is introducing the same functionality

    Right, but isn't that the point that now they can't track you across sessions based on logins and things of that nature. If I use the app on my phone, they can't check my browser history against that and, on the Mac, they can keep my login information but they can't track me across sites. Seems like a win-win for users on both ends.
