While not a committee member, this is tolerable and workable.
We can assign a /48 to every tower (POP) and that will geo locate
good enough for the rural area. Geo location by address doesn't
work that well in our rural area anyhow. Can be miles off. But
using tower location will get it into less than 10 mile geo location.
One comment is that most providers that I have dealt with are very
reluctant to swip anything less than an IPv4 /24. This no longer affects
me because these providers are in the process of reclaiming their IP
space when we shifted to fiber. One was nice and one wasn't, but we
basically had to shift all customers to NAT since we didn't make it in time
to get our own IPv4 allocation. Getting an IPv6 allocation is waiting on 
our fiber
provider providing dual stack and the issues you are some what addressing
in this current policy making.
