Does anyone remember the phrase, "4 Iron Rough?" (i.e., rough where 4 iron the longest club you can hit out of it) I heard it around Chicago when I first got in the biz, and it was debated as sort of out of date then. It certainly precluded short hitters or muffs from reaching the green from their max distance, so in a way, was at least intended as "proportional punishment."
I guess in that theoretically perfect idea, carried too far, short holes would get even higher rough than medium or long holes (i.e. 7 iron rough on short par 4 holes?)
In general, I would say roughs have gotten shorter over the decades, again trying to move short hitters and wild drivers along in their pace of play (with rough deep enough to cause lost balls or extensive searches now verboten) But, as in the WF example, there will always be a few courses who want to be known as difficult and they can mow it longer if they please.
As an architect, I don't really care that much. Good players can generally be affected by reduced spin (forgetting top tour pros and their 130 MPH swings) by 1.5-2"" rough, which allows lesser players to find their ball and hit it (which is always fun golf) advancing it at least most of the way to the green.
Just MHO.
