It could. However this would also add a filter on 'scope global' for
ipv4 which isn't present at the moment. Not sure if this would affect
anything in practice ...

However since dom0_ip and dom0_ip6 need to stay separate (ipv4 is
mandatory and 'fatal' out if not found, but ipv6 is optional), I'm not
sure how useful it is to really combine there.

Yeah, I had to re-read the doc :)
