Note that the needs_recovery flag was INTENTIONALLY made incompatible, not "wrongly" so.  That is because with metadata being written into the journal, there is no guarantee that the filesystem is even consistent when mounted without journal replay.  Metadata blocks can be reallocated as data blocks and overwritten by data, based only on changes committed to the journal, and this could result in errors.
