Well, if the android people keep rejecting all sensible approaches to
power savings except their suspend blocker mess, then I don't see why we
should support their ill designed mess.

We should strive to provide an interface that can be used by all
interested parties to conserve power; if Android really is the only
possible user of the interface then I don't see any reason at all to
merge it, they might as well keep it in their private tree.
