LSN is required when access providers come across the following two combined constraints:
1. No more IPv4 addresses to give to customers. 2. No ability to deploy those customers on IPv6.
2 has little bearing on need of LSN to access v4. Insufficient amount of IPv4 addresses => LSN required.

No, if you have the option of deploying the customers on IPv6, you don't need LSN.
The problem is that until the vast majority of content is dual-stack, you can't deploy customers on IPv6 without IPv4.
cough cough NAT64/DNS64 ...
cough DS-lite.
DS-lite is a slightly less pathological form of LSN. It's still LSN, it just removes the second NAT at the CPE. Owen
