ResourceModel not complete for sub resources

So I am trying to vist the model provided by ExtendedResourceConfig; but I am finding that the information for sub resources is missing. The example attached to this issue is suppose to create a map of Resource class to path to aid the delcarative linking code; but it only iterates down one level.

This means that the output of the code is:

GET ..../root
class project1.SubResource : /root/

{sub}

rather than the expected

GET ..../root
class project1.SubResource : /root/{sub}

class project1.SubSubResource : /root/

{sub}

/

{subsub}

Note that the single resource method for the GET operation is also missing from the SubResource Resource instance. This may or may not be part of the same issue; but would ideally be fixed at the same time.
