Currently the kobject implementation is pure and well-defined. It is
a good implementation [kobject], and I'd hate to see it lost into being
convoluted with/into another model.

Currently the infrastructure layers are well defined:
kobject -> (A layer with objects, their behavor and implementation)
device -> (--"--)
sysfs. (--"--)
This isn't that bad of an infrastructure.

It is this well defined layering, i.e. objects, their behavior and
implementation, that allows different (better/worse) infrastructures
to be built on top of it.

It is this well-defined layering which will allow what Tejun wants
to be implemented.
