Not a zero sum game. The likely resources mostly aren't working on
IPv6 right now regardless.

More like ramping up the manufacturing of oil booms independent of the
experts daily activities since the experts really aren't needed to
explain how to manufacture a plain old oil boom.

I hear exactly zero chatter in the ops forums about bypassing dual
stack in favor of going direct to native v6. I know some work has been
done on nat64 but are you aware of shipping COTS products designed for
enabling large scale collections of native v6 clients to communicate
with v4 servers?

Unless something changes, the transition is to dual stack. Which
requires an IPv4 address. From somewhere.
