Hey there,

you might be interested in:

  * https://blueprints.launchpad.net/ubuntu/+spec/client-1303-add-app-model-and-lifecycle-to-platform-api
  * and the corresponding spec in:
https://docs.google.com/a/canonical.com/document/d/1ij8RtPsR_eYMW3mys8Gu1Y2CVFZpjXdMpdIjIGZ1SCA/edit#

In summary: We will implement a very strict lifecycle policy, too, and
one that seamlessly adapts and extends to different form-factors.

Thanks,

  Thomas
