I think this is a code and process implementation issue on the CPE. It
would be too burdensome for the BNG to check and manage this.

Not necessarily. The only concern will be if customers churn, and you
need to recover IP address assignments tied to usernames that are no
longer in-service.

It's less than ideal, but static assignments override the automated
nature of RADIUS, which would make the process more reliable, but less
scalable.
