Oh, actually I just tried that out and software_node_register_nodes 
doesn't allow this (parents must be added before children).

So I still think software_node_register_nodes and 
software_node_unregister_nodes are made more useful if children are 
removed recursively. I'll make some changes for v2 to make the change 
less far-reaching + better documentation.

Thanks,
