This is not an acceptable implementation.  It causes the disks to spin
down when you're doing a "reboot" -- which puts considerably more wear
on the drive than an "emergency retract" ever did, and is also really,
really annoying to wait for.

Furthermore, doing an "emergency retract" was never a big deal in the
first place.  Who cares?

Please back it out at your earliest convenience.
