I think for on the road, it is of very limited value. If you are off-roading it, may make more sense to mix it up.
Many road cyclists (myself included) like to "rotate" our tires, when the rear is worn we move the front to the rear and put the new one on the front. That makes using the same width tires more important.
But as I stated, there is no harm in mixing it. YMMV.
