Not sure what that research is supposed to prove. No copy-on-write
filesystem should ever try to modify deleted data OR meta-data in-place
until the block is actually reused for something else. It would be a
complete waste of I/O, waste of SSD erase cycles, and waste of time.
A data recovery tool algorithmically designed for a more traditional
copy-over filesystem is not going to work well on a COW filesystem,
period.
