Actually, no. Some courses are subtle and some by-gone ideas are way beyond comprehension today.
I'll give you just one. Camargo had a couple of medium to short par-4 holes which had fairway bunkers set into natural slopes, 165 to 200 yards off the tee -- where a good modern player would never think about them. The green committee wanted to "move" those bunkers more into the driving zone, but I resisted, because I knew we couldn't build a fairway bunker on the flat, high ground that was in keeping with the rest of the construction. However, that answer wasn't enough for the green committee -- I needed something more.
Eventually, it dawned on me. Both holes in question were slight doglegs, with the bunker on the inside. The 165-yard bunker was on a 340-yard hole, and the 200-yard bunker on a 400-yard hole -- which meant that THE MEMBER WHO COULD JUST BARELY REACH THOSE GREENS IN TWO, had to flirt with the bunkers in order to do it. So the bunkers were entirely relevant to a certain class of player who happens to be well represented in the membership at Camargo.
But I never would have figured that out if I hadn't been struggling for a reason not to mess with the course. And I'm convinced there are a lot of other things like that in older designs, that are being messed up in all these recent restorations.
Because unfortunately, sometimes the architect's intent is to make money doing restorations. Present company excepted, of course.
