The issue was that UnitStep was being used sometimes as a piecewise function and sometimes as a distribution. HeavisideTheta was introduced to take on the distribution role, so that UnitStep is now just a piecewise function. Also, UnitStep[0] returns 1, whereas HeavisideTheta[0] returns unevaluated.
