Someone at MS is just pulling this out of their asses to try and cover that Microsoft has no clue what they are doing.
So they were able to easily query the code for a few thousand applications online that made this version check mistake. Big deal.
Compare this to how many applications out that that have broken because of other minor OS changes combined with bad programming. I've seen piles of that myself, and Microsoft never bothered this hard to keep compatibility for any of those.
