This part is wrong, or at least it doesn't explain the real problems behind our demand/supply.

First, items *do* have dependent state, since every supply is backed-up by a kernel controller context.

It's the way we have it implemented.
Currently we add/register all supplies from BeanMetaData at Installed state. So no way of knowing if some supplier can supply the supply before (a lot of supplies here :-).

We can extend the supply notion in a similar way we extended installs, to be applicable in any state.
Then having

  | Map<ControllerState, Map<Object, List<KernelControllerContext>>>

in AbstractKernelController.

Definitely not. :-)
