It breaks mobile nodes. The HA sends traffic to the MN using a type 2 RH header. That is, instead of "tunneling", e.g., via IP in IP, the HA forwards packets to the MN at its temporary Care-of-Address via a type 2 RH header. The HA can't communicate with the MN if such traffic is filtered. Hence, if such filtering becomes even occasionaly common on the open Internet, MIPv6 will become unusable/undeployable in practice.
