By requiring a similar  level of information and review about the V6 deployment
that today is received about the V4 deployment.

Essentially:  This just *changing*  the existing utilization criterion so that
only IPv6 networked hosts that are assigned IPv4 can be counted to reach
the 80% utilization threshold for IPv4.   The IPv4 addresses are deprecated
and allocated solely to be used for legacy interoperability with the same hosts
that are already IPv6-enabled.

For example, if an IPv4 /24 is already held, and an additional IPv4
/24 is requested.
Then ask for the count of IPv6 enabled hosts that have been networked and
assigned IPv6 addresses  in order to meet the  80% of  addresses in
use threshold.

The number of IPv4 addresses actually in use on that subnet doesn't
need to be a
factor any longer   (active networked IPv6 host count  Instead of,
not in addition to IPv4 host count).
