Compat features are not always related to special inodes. For example, the COMPAT_DIR_INDEX feature is for the directory indexing and has nothing to do with special inodes. In this case, defrag shouldn't break the indexing, but it depends on each specific feature. Hence my assertion that defrag needs to understand EVERY feature flag in the filesystem before it touches the filesystem.
