I have though about this, and basically come up with one little
issue: We have so far assumed that service dependencies can be
declared at a Type level - i.e. it is a property of the component
itself, and not something that is configurable.

However, if the component is a container, the sub-components 
inside it may have dependencies that cannot be satisfied by
sub-components but must be provided to the container-component
by its container.

This use case, where the dependencies of a component is determined
by the components inside it, isn't accounted for.

One solution is to subclass the container class and add deps
to the subclass.
