Yes. Existing software limitations make it difficult to impossible to
run a reliable 3GPP network at greater than around 40% utilization of
addresses versus connected subscribers. Current ARIN standards require
80% (?) utilization.

Dual stack: IPv4 CGN plus IPv6.

This problem is not unique to 3GPP architectures. Virtually every
eyeball network has a version this problem with similarly scoped
technical limitations. The ship sailed on solving it with more IPv4
addresses years ago. What's "special" here that makes it any different
from everybody else's unmet need?
