One of the early promises in WG discussion was identification of
how production networks that actually use SNMP for configuration.
To support the (implied) claim that this is common in section 6,
at least some such networks should be identified. Did I just miss
this on the mailing list? Or when was it posted?

An issue which was framed more crisply in the Policy Framework WG, but
still applies here because policy configuration is advocated, is the need
to control which persons can modify (possibly even read) which
configuration items. It is well known that different persons or teams
are responsible for different configuration parameters on production
networks. It is not clear from the relevant section how different user's
access is controlled to different items. For example, where is the
control information stored?

How can the "new SNMPCONF technology" be the subject of "best practice"
without distorting the very idea that technology has been already found
effective in practice?

Please do not simply repeat the refrain that these fundamental problems
have been addressed already, or that they are (surprisingly) appearing
only at the last-call stage of discussion. It appears they have not yet
been actually resolved.
