Indeed, what RFC 2578 does have to say about the matter:

7.10
...
|  Note that the final sub-identifier of any administratively assigned
|  name for an object shall be positive.  A zero-valued  final sub-
|  identifier is reserved for future use.
...
8.5
...
|  administratively assigned name.  In order to achieve compatibility
|  with SNMPv1 traps, both when converting SMIv1 information modules
|  to/from this SMI, and in the procedures employed by multi-lingual
|  systems and proxy forwarding applications, the next to last sub-
|  identifier in the name of any newly-defined notification must have
|  the value zero.

This taken together leads me to believe that *embedded*
zero sub-identifiers are currently perfectly legal.  The only
restriction on the use of zero is for the final sub-identifier
assigned in an OBJECT-TYPE.

Am I missing something?
