Patrick,
Once again a great topic. Timely for me. I was on a site visit yesterday and am trying to build a more old fashioned course, including a few holes with "chocolate drops" as you discuss.
The shaper was having trouble understanding the concept but then said, "So, you're saying to build it like they built it before they knew what they were doing?"
That's a perfect description of these features built when no one was self conscious about golf architecture. (Gca fans sent critiques via carrier pigeon, so it took a while for them to become unpopular!) As time went on, those went the way of a lot of other features that got larger to accomodate bulldozers vs horses, smoother, as we "got to know better" and different.
Our nostalgia now gives these unnatural little features a better looking form.
