At this stage one still needs A records to be reachable by everyone. One should also ensure you are reachable over IPv6 as lots of the world behind IPv6 only links as their ISPs don’t have enough IPv4 addresses for every one.

Would the lack of A records affect pointer records? Seems like it would.
