I'm afraid I don't understand the question exactly. If you have a local
redistribution for local staff, you probably don't want anybody (outside
from the local staff, which I assume will know about it) to subscribe to
it, and it should therefore not be known to the rest of the world. A list
which isn't peered doesn't provide the same service as the master list,
and therefore it is absolutely reasonable not to forward subscription
requests for that list to a redistribution list - again, another reason
for not being globally known. I cannot think of any reason for wanting to
be globally known; did I miss something? :-)
