There's no frustration here. I'm just observing that this seems to be a non-intrusive way to provide a value-added feature for Nikon's users, with very little downside due to the particular nature of the A-S mounting system (vs. say, Manfrotto's system which would interfere significantly with a photographer's choice of mounting systems).
The wheel analogy is spurious at best. There are many performance and aesthetic reasons why wheels vary. If we can bring it back to cameras, I'm glad that we've come to a conclusion on a couple well-defined memory cards, casting off MemoryStick, XD cards, and the like. I'm pleased that the tripod mounts on our camera bodies are all one size. And I would be happy if, when I purchased a lens, I could use a mounting standard that is adopted by many manufacturers.
(yes, I know it's not a ratified standard by a regulating body, but that's just semantics)
