%sam - If this MIB allows write access, do you/WG anticipate, any extension to the MIB should also provide write-access as well? For example: http://datatracker.ietf.org/doc/draft-ietf-bfd-mpls-mib/ augments this base MIB to support MPLS. It adds more confusion than solving the issue as base MIB supports write-access, but augmented/ MIB extension doesn't. 

As the BFD MIB authors were not supportive of write-access objects in the MIBs, why to have them in the first place?
