Why not just make it a Mac feature as opposed to a Safari feature? This feels a little like Microsoft trying to integrate IE into Windows.

I think even most of Microsoft's critics agree that the criticism over integrating IE and Windows was pointless. Basically every major desktop and mobile OS does the same thing these days.

Also, Safari is only released on OS X. So I'm not sure what your first sentence really means either.
