ejecting mounted media possible after `cdcontrol play`

when `cdcontrol play` is used with a mounted data cd or dvd the following
message appears (only when running the cdcontrol shell):

"Device not configured"

since there are no audio tracks on a data cd or dvd it's obvious cdcontrol
will fail. however after issuing the command the drive lock gets removed. now
it's possible to push the eject button and remove the media even though it's
mounted. is this a bug or a feature?
