I think it is because there is too much data to push up the tree to one
manager.

In general, this information can be exported via SNMP or whatever the
management infrastructure is.

BTW, are there SNMP MIBs for all of this information ? To my knowledge,
some of these were started but never completed. Also, the MIBs were
geared at the agents rather than the managers (in the PerfMgt arena).
