There are potentially a number of aspects to be considered here
1) The amount of currently allocated space that would/could be freed
2) The number of contiguous extents of storage that space release would be issued for and hence the complexity of the release processing - and the time
3) The replication status of the volume and whether this might cause issues with space release - perhaps not practical to determine given variability but still a desirable user aim.
