There is already a method to achieve something similar, which includes using speed distributions. If you specify in the vehicle type a speedFactor (which acts as a multiplier to allowed speed on the lane) and a speedDeviation (acting as a relative standard deviation to the value above), sumo will calculate a vehicle specific factor how the vehicle tends to obey the speed limits. If this factor does not fit the departure speed it is recalculated. The reason why we probably won't implement the direct fix you mentioned is, that if your vehicle has a departure speed which is higher than its maximum speed then there is obviously something wrong with your configuration because the vehicle's maximum speed should never be exceeded. We should implement something which draws again from the vehicle distribution if the depart speed does not match the maximum speed, but for the moment it is probably easier if you run a little script on the generated route file which fixes the vehicle type depending on the depart speed. (In fact, we already have this script, if you want we can share it.)
