From user POV semantic is wildly different: with Ext3 I'm guaranteed my P2P state will not be corrupt - no five seconds window. With Ext4 I'm almost guranteed it'll be destroyed in crash. Big difference.
Granted - it looked like "more-or-less" the same mode from filesystem developer POV, but that's no excuse... May be it's accident, may be not - but semantic of ext3 and ext4 ordered case was quite different...
