Agree with your assessment. It depends on the property. Some examples not
tied to a network map are Metered or not, subscribed bw, or rack number in
a previous DC example.

Good observation. The requirement of adding pid came from a previous
review. Suppose we keep the requirement. I see your observed problem of
multiple network maps, and if the request specifies only pid, which network
map. Given that we will likely (1) require at least one network map, (2)
specify one as default, then the response to a pid property query returns
the result based on the default map. We should allow the pid query to
include the resource id of a specific network map to handle the general
case. Does this address the problem?
Thanks!
