These developments in golf, like the post-war trend towards championship tests and Par 72 courses, they don't come out of thin air, do they? They must serve someone and/or some kind of want or need, and they wouldn't have much staying power unless they had fairly widespread buy-in -- ie unless they served many multitudes and satisfied a popular/common want.
I love par 4s, am ambivalent about most Par 3s, and have liked par 5s only occasionally (and loved only one that I've ever played) -- and yet, even I can see the 'validity' of the Par 72 model in terms of the 'variety' of golf holes it offers and the 'balance' it provides and the 'needs/wants it meets' for various levels of golfers and simply for its peaceful 'symmetry' and the 'ease of comparison' between the front and back 9.
Again, I don't really need any of that, as my own ideal Par 72 is 16 Par 4s, 1 par 5 and 1 par 3; but I can certainly understand why the ten-4s, four-3s, and four-5s model has such lasting appeal.
