Tom D's "kitchen sink" remark hit home. We recently completed The Short Course at Mountain Shadows (AZ) and had 19 greens to create. While I had considered a "green bunker" over the last 30 or so years, it never came to light...until now. With 19 greens to create, and one shared, I decided that using a bunker to divide the double green could work, and be fun and novel.
It is basically an L-shaped green where each hole pays into a prong of the "L". The small bunker sits toward the L's angle where a hole location waits for either hole in the situation where the staff wants to put forth "something different."

I an inclined to think the green bunker should NOT be overused, but with 19 greens in a single 18-hole round, I overcame the "kitchen sink" rut and decided it could make sense, and be a new experience for nearly all golfers.
BTW ... I also had the Tillinghast "bump of narly grass" within the green idea, but suppose this fell the way of "the laundry sink..."
