I've never seen a Cisco device that supports this, and I spend a fair 
amount of time grubbing around inside snmpwalk output when new IOSes 
appear.

Granted that the @vlan is a (tiny) bit tedious to implement, what's 
inaccurate about using the indexed mode?

One thing to note; the rest of the dot1dBridge mib also changes when 
using indexing; in particular if using PVST, the STP-related items are 
the per-vlan ones too (root, root port, etc.) which is actually really 
useful.
