As for the KAME's implementation, no. Actually, the "special code" is
a special case of sending redirect messages, and the entire part
follows the first paragraph of RFC 2461, Section 8.2:
8.2. Router Specification
A router SHOULD send a redirect message, subject to rate limiting,
whenever it forwards a packet that is not explicitly addressed to
itself (i.e. a packet that is not source routed through the router)
