The limitation was fixed in 3.7: https://bugzilla.kernel.org/show_bug.cgi?id=15762 I think the btfs developers understand quite well how filesystems are supposed to work. As best I understand it, the limitation was a result of back-references, which are an important feature to keep inodes from ending up as orphans. If you're going to have an on-line fsck, that matters.
