Sure, see my comment on adjusting the lifecycle policy below.

Again: We can dynamically switch to a different lifecycle policy if
the phone is docked or charging.
A phone is a different form factor and usage scenario than a normal
desktop PC and thus, the lifecycle policy is different, too. In the
end, we want the Ubuntu Touch to be used by people who potentially
don't even own a laptop or a desktop computer.

That's an interesting way to put it: Let's phrase it this way: Users
do not need to care, the state of an app is completely transparent to
them.

Well, we are doing preemptive multi-tasking, too. We just reserve the
right to aggressively take away resources from non-focused
applications.
