I know this has been brought up multiple times. As I was reading Apple SDK site for GameCenter. Does this mean is possible now?

But can’t you see profile pages on older versions of iOS/macOS?No, that's the SDK for game developers - you can only access data for your own game through it.
GameCenter currently lacks any sort of profile pages that list all of the users games. You also can't search for users across the entire platform, it only lets you do it on a per-leaderboard basis. Would need both to add tracking support for it.
