I've always wondered, too.  My tentative answer is that different
missions require a different orbital inclination, and hence a
different amount of roll; hence, the capability is needed no matter
what.  Therefore, you may as well use it on every flight, and
optimize the launch assembly for other criteria, i.e., ease
of travel from the VAB.
