This sentence makes grammatical sense, but already fails at the semantic level. Deleting zoned RT extents goes through exactly the same metadata updates for the bmap and rmap tree, but instead of updating the allocation btrees it just updates a counter in the rmap inodes. So it requires a very similar, but smaller metadata update.
