It's a cargo cult style extension of a not particularly useful IPv4
convention to IPv6. A much more useful convention that happens to be
easier to implement is that hosts with static addresses have rDNS and
hosts without do not. That would be a lot more useful to all involved.
But again, at M3AAWG, this seems to be a settled topic. Anyone who
expects rDNS for dynamic IPv6 addresses is an outlier.
PS: Have you figured out how to do DNSSEC on dynamically generated reverse
zones, both for results that return PTR and results that return NXDOMAIN?
It's possible but it's not trivial.
