I'm not sure how a new OS update that changes more things than usual is fragmentation, especially when that OS has a very small number of devices that it runs on and a user base that by and large quickly updates to the new releases. It might be more of a disruptive update than usual, it might be good or bad for users in the short term, it might be good or bad for developers in the short term, but it's not fragmentation.
