The problem isn't the OS, it's software like SVN that didn't support junctions until much later than junctions were introduced into Vista (and backported to XP).

And then projects need to use the latest versions of those software in order to benefit... and that's assuming the feature support is stable.

As late as 2009, our windows project devs (at my old company) were at a disadvantage to OSX, Linux users.
