draft-ietf-lpwan-overview is overview type of documents, so that makes 
sense.
In this example, we speak of competing or overlapping efforts. At least 
some people see it that way.
So explaining the relationships between those efforts in a way that will 
satisfy everybody seems very difficult, if not impossible to me.
In those of situations, my view is pragmatic: let the market decide.
