The question is, should there be another one?
It's a distinctive feature, and I have to admit that during the L.A. Open I always hope a pro has to take out his 60 degree wedge and lob one from one side of the green to the other, over that bunker.
But I wouldn't be in favor of building a bunker within a green on any other course. There's the maintenance issue of people using wedges on the green, for one thing (and I believe you should never disalow that shot. If you're going to present players with that specific problem, you should allow them to address it any way they choose, within the rules.)
In addition, the game's hard enough without the members storming off to the next hole muttering to themselves, "Even when I hit the green, I'm in a @#$@#%$ bunker!"
