Well, it's not much help. It seems possible to "corrupt" a primary superblock that points to a corrupt tree root, and use btrfs rescure super-recover to replace it, and then mount should work. One thing I didn't try was corrupting the primary superblock and just mounting normally or with recovery, to see if it'll automatically ignore the primary superblock and use the backup. But I think you're onto something, that a good superblock can point to a corrupt tree root, and then not have a straight forward way to mount the good tree root. If I understand this correctly.
