I think that is a good principle.

I concur: blanket exceptions are not the way to go. The way to go is
ensuring the lifecycle model is not simplistic and reflect the fact that
"losing input focus" (for example) means far less on a "general purpose
computation device" than on a "phone" and something in between on a
"resource constrained monitor"

And we need to correctly identify the modes of operation the system
needs to support and how the user controls them. Users can cope with
laptops that "hibernate" and "suspend", they can cope with power modes
on phones. And if we have "convergence" then all these modes need
merging into a model users can reason about. That will take time.
