If by "left as defined" you mean what's in RFC 2863, I agree.
If you mean what's in draft-ietf-ipoib-ibif-mib-05.txt, then I disagree.

If multicast is defined for this interface type, it seems  clear
that ifInMulticastPkts must be incremented each time such
a packet is delivered to a higher sub-layer.  Same reasoning
goes for the Out and HC counters.

Putting this information in a vendor-specific MIB, and mandating an
incorrect implementation of the IF-MIB standard, would seem to me
to be the worst possible solution.
