I would like every A-M.root-servers.net have an A and AAAA record.
I don't care how the root-server operators decide to partition to workload
among hardware. Over time we will need more v6 responders and fewer v4
responders.
I don't think that there is, or should be, any requirement that v4 and v6 be
answered by the same system, and given anycast, they might even be in
different locations.
I think that the current text captures this just fine:
The root name service:
...
MUST support IPv4[RFC0791] and IPv6[RFC2460] transport of DNS
queries and responses.
because it focuses on the root name *service* from an external functional
point of view, and not from a design point of view.
