If you think the move towards accuracy and away from hacks is sudden, then you clearly haven't been reading the progress reports or been following Dolphin's development at all. Having per-game aspect ratio hacks doesn't even make sense, since as MaJoR pointed out, if Dolphin isn't emulating the way a real GC would scale its games, then the solution is to implement that scaling ability so that all games get scaled correctly. Making per-game hacks would probably be more time consuming than fixing the actual problem, so even if the developers weren't moving away from hacks (which they are), it wouldn't make sense to address the problem that way.
Also, this isn't even your thread, so it really isn't up to you to decide what its purpose is.
