We have had in-depth discussions about this specific policy decision
on this list. While it is strict it also allows us to guarantee great
battery life no matter which applications are installed. And: we all
agreed that we will factor out certain type of background tasks into
system services to support common use-cases like navigation apps or
Instant Messaging services.

If you have concrete ideas for additional system services, I would
propose kicking off a new thread on this list.
