So right now our fsck fixes anything wrong in the extent tree, which is where a majority of the problems happen. The other side of course is the fs tree which is infinitely easier to deal with, but I usually wait for a user with a broken fs to fix before adding the ability to fix it into fsck so I'm sure we have a good testcase to work against. Every fix I add to fsck gets a test image added to btrfs-progs to make sure we're never regressing. Obviously we aren't in xfs/e2fsprogs territory, but it'll fix 90% of the problems and then the other 10% are just a matter of having an example to work off of.
