Automatic periodic fscks have long annoyed many people and don't do any good, which is why we have stopped doing them on internal disks. It would likely be much more of an annoyance on removable media. Ext3/4 don't need such checks even if you unplug them without unmounting. For the filesystems that do ( fat, ntfs ), we don't have a way of detecting when they need checked, or decent tools to properly check them anyhow.
