Some thoughts about this approach. I wouldn't put abstract definitions into Controller (under Descibed), as I think they would do more harm than good on the overall impact. I would keep them in some nice, useful registry, where I would also be able to define proper dependencies on them. e.g. real bean deployed before its abstract parent, would mean dependency item on this abstract-registry This should be an impl detail of AbstractKernelController, where the real abstract handling code would be separated. Or why would you want to keep it as part of Controller? Wrt Properties. I guess both of your use cases proved we need better impl. Kabir, can you please have a look at what we can do there?
