I think the only reason they don't do this is that it gives the control system the flexibility to have a very short cycle in one direction (ie, one or two cars through).
As soon as you default to always having a walk, you effectively set the absolute minimum cycle time in that direction to however safely someone can slowly walk across. There are probably standards that dictate the speed at which this must be calculated.
