Things are the way they are because many devices predate the final SBC spec. They report LBPME=1 but do not have the VPD page indicating their preferred deprovisioning command. The VPD was added very late in the spec and there are a ton of devices that don't have it. As a result, we default to WS16 unless the device reports the UNMAP parameters in the Block Limits VPD. That has been a very solid heuristic for a long time so please don't mess with that. -- Martin K.
