If 1) happens without keyboard or mouse attached that definitely counts as a bug
As for proximity - the main issue is there's no API to query the current state of the sensor (as Alexandros mentioned).
However done properly the power drain should be minimal as it should only be turned on during an off to on transition (at least to handle the cases described here).
