configuration: writable MIB modules versus NETCONF/YANG modules

Dear all,

We occasionally see read-write MIB module proposals within the IETF.
However, the write capabilities of those MIB modules are rarely implemented.

While discussing this issue with the MIB doctors, we arrive to the 
conclusion that it's now time to set the direction for future MIB 
developments within the IETF. Basically, let's not specify read-write 
MIB modules unless we have a good reason. Read-only MIB modules are 
still fine though, as SNMP is clearly used for monitoring purposes.

Here is the statement we came up with:

    The OPS area recommends the use of NETCONF/YANG standards for
    configuration. IETF working groups are therefore encouraged to use
    the NETCONF/YANG standards for configuration, specifically in new
    charters. SNMP MIB modules modifying persistent configuration state
    should only be produced by working groups in cases of clear utility
    and consensus to use SNMP write operations for configuration.

Ideally, this should become an IESG statement.
Your feedback is most welcome.

Regards, the MIB doctors & Benoit
