I feel that for the most part it is desirable, and that is why vector drawing programs allow you to have sharp joins on path strokes.

Think of the spread thickness as equivalent to an extra border around the pre-blur shadow box, which is the same color as the shadow, and where 'border-radius' is for the inner edge of the border instead the outer edge.
