RJ,
The walk-off areas you shown in the pictures you provided are very often overlooked in golf course design. When considering such areas, it is a good idea to think about multiple exit points. Examining the pictures closely, there does seem to be a lot of wear & tear at the walk-off areas, creating playability and maintenance issues due to the high traffic these areas recieve.
To the original post regarding Pete Dye's front exit, that is an annoying feature. It will slow play, because players will remain in reach of the proceeding group for a longer period of time. It also tends to interupt the flow of the routing, which may be a minor quibble regarding the course architecture, but not the golfing experience.
