I beg to differ. There is no way to tell whether it's an "extremely tiny" sample, as Apple simple will never tell us the percentage of affected units, and the experience of a single user, whether positive or negative, is statistically insignificant.
No one is saying it has to affect the majority of units, and if you haven't been hit great for you. I also agree about not worrying about problems until you face them. But at this point negating that an issue with the 2016 keyboards exists, when Apple techs themselves are starting to admit it, is pure denial.
And I think it's sensible to at least warn potential customers that the keyboard is prone to failing (which does not mean it will certainly happen but that there is a concrete possibility that it will at some point) before they drop 2k or 3k on an expensive machine.
