I believe  details  was intentionally omitted to receive some feedback
regarding
concept basics only, this may help to adjust (or change) implementation
details
from the beginning.

But ok, as you aren't arguing against those basics and intentions then
seems you
agree to them.

For me, there is a point that seems debatable already at the starting stage:

Sometimes it's quite reasonable to make decisions (or policy)
at the low level, without exposing events to higher layers,
e.g. turning a clock off when reference counter gets zero, this is
what OMAP's clock framework currently does.
