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?
