Generally, if you are going to include run-offs, then they are much better to be taken through the first low point at least; so that they stop on an upslope, promoting balls to remain on short grass.
That’s certainly the way I like it on links land, widening out the green complex, making the whole area look more pleasing to the eye, and giving a putter option for higher handicappers whilst giving good players options / doubt. Even better if they go over the next high point so that the transition to rough is hidden to the approaching golfer’s eye.
You may be coming at it from a slightly different angle on US courses, Jason? But I can’t see what you describe being more than a half measure.
