Michael -
I completely agree with your statement. Yes, if the dell hole was built today, I think people would scream from the mountain tops. The quirk you mention seems to be enjoyed, even celebrated, on older courses but if a newer courses has something like that, people flip out. A big part of the attraction of playing golf in Ireland, for me, was getting to play on courses that have some quirk in them and have design elements that you don't get to see every day here in the states. It seems a double standard does indeed, exist.
Actually, the dell hole was recreated at Erin Hills, which I played in 2008. The two holes were remarkably similar. I could be wrong, but I believe the dell hole at Erin Hills was elmininated during the redesign of the course.
