Yes this claim seems rubbish to me. It is true that the AdaCore BB run-time idle loop is a busy loop which doesn't enter low-power mode, but this can be implemented by a lowest-priority task with an infinite loop entering low-power mode.
On a LEON3 platform we assigned the lowest priority to the environment task and implemented such an infinite loop in the main program. It works very well.
