"Most" people I was referring to those on this forum. And besides the Kilo TT owners how many of the forums members do you see, just browsing the Photos thread, with "stock" bikes. In fact when most get their stock bike they jump on here asking for recommendations on replacing everything. Before it was automatic Sugino75s and now it Omniums. In fact while we talk about crank arm length, I doubt that that was what the OP was asking, I think he's asking about chainring size since he mentioned, cog size.
