REQUEST SENSE is also used as an independent command to determine the
power state of the device.
See the description of the REQUEST SENSE command in SPC.

For protocols that use autosense, probably not.
For protocols that do not have autosense, you bet. (There are quite a
few wide spread protocols that do not have autosense capability).

	Since some protocols use autosense then the sense data will be
cleared when a command creates the condition and request sense will just
get back "no sense".
	Is there a case where request sense is still useful?
