I too agree the v4/v6 stuff is pointless and slightly annoying so I have been using same name with A/AAAA records.

I agree that using the v4 or v6 tag in forward or reverse is pointless.  One can tell it is v4 or v6 by the result of the lookup and the hostnames don't change just because they are accessible via IPv6.  If a hostname is directly related to the fact that its IPv6 by all means put it in there though.
