It's not. We are talking about fixing problems users start to experience when they switch from ext3 to ext4. None of the other goals, such as fixing all the apps, making all filesystems happy, feeding the hungry and making world a better place are being pursued here. The 2.6.30 fixes do what they are supposed to do, without breaking anything else. So it is a good thing, and I don't understand why you seem to be against it.
Sure, there's lots of stuff which ain't working right, but it's not a subject here. World's not perfect, and it's not going to be any time soon.
