Subject: Space Maps?

Cleaning out some old research papers I came again across the proposal
for "space maps" in ext4 [1]. What happened to that? Was it rejected
due to too much risk or other technical reasons? The benefits sound
appealing, so I was wondering if there's something fundamentally wrong
with the suggested approach.
