Hi Ole, IMHO, it is high bar for the operators to support dynamic routing protocol for residential customers. Today, each access router can easily support thousands of customers. Imagine the access router needs to receive thousands if not millions updates every few minutes, I am not sure the route process is built to support this kind of load. Besides, if the CPE is compromised and inject some routes didn't belong to it, it will create security issue.
