Are you an English teacher or something? Because it sounds to me like you're doing a hell of a lot of reading between the lines. Just because I don't automatically equate every new feature on a bike with instant superiority, that somehow makes me closed-minded? Is it now so thoroughly out out vogue to care about serviceability? And how in the hell did this even turn into an old vs new conversation anyway?
Hell, it wasn't so long ago that I myself was thinking of ways to put the swingarm pivot point and countershaft sprocket on the same axis. I thought it would be a good idea, for all the reasons that have been pointed out here. But then I thought to myself, "Self, how in the hell would you be able to work on this thing? And just how much benefit would the rider be getting for that sacrifice?" On those grounds, I decided that it was fine the way it is, unless someone can come up with a way to make this happen without making the bike too complicated to work on. If Husqvarna have managed to do that here, then I applaud them on their ingenuity in managing to make things genuinely better. However, I am skeptical that the above has really happened. The last thing I'm going to do is buy one of these new four-strokes, run it until the front sprocket looks like a saw blade, and then start giving preliminary thoughts on whether I like this new development. If you apply that standard on me for disapproving of it, then go ahead and apply it to everyone who likes it, and make them buy the bike before giving their opinion. And in this spirit, I'm going to announce that I don't think Antarctica is a cold place. It might be, but I haven't frozen to death there yet. I've heard stories of people freezing to death there, and I've read plenty about the climate and the average temperatures, and compared that with my own experience, but we all know that "logic" nonsense doesn't count for anything.
