I just wonder if this is anything really unity8-specific. We've not
created special APIs (at least not compared to Qt ones), we're not
actively killing apps for no reason, it's just that we're more resource
constrained and OOM killer kicks in quicker. When closing apps, we do
tell apps, after waking them, when the user closes them, so they know
they need to save data (we're not giving them a chance to prevent
closing, at least not yet).

Well-behaved apps (LibreOffice, Firefox) do this already by periodically
saving restore information, would you consider those as "supporting the
unity8 lifecycle"?
