In some regions Google has revere DNS for IPv6 already:

They're doing it at about the same level as their IPv4 reverse DNS,
that is, servers seem to have reverse DNS but intermediate hops in their
infrastructure do not:
Ryan-Rawdons-Work-MacBook-Pro:~ ryan$ traceroute mail.google.com
traceroute: Warning: mail.google.com has multiple addresses; using
