Obviously, the intent is not just to have the function for certain values, but to employ other powers of sage, including differentiation and integration (not forgetting that the step function is the integrated delta function). There are, though some other problems with implementing those, including lack of support in the packages sage uses (there's some support for it in maxima, through the laplace transform). Yet, some stuff might be hard to implement, notably plotting, which is very useful. Currently, usage of lots of step functions is easier with numerical data, but that still isn't optimal for some applications.
