I've not closely followed the most recent version of FreeBSD IPv6
code, but the use of the routing table in ip6_input in the original
KAME implementation had nothing to do with the strong host model.  It
was just for faster determination of whether an incoming packet is
destined to *any* of host's IPv6 addresses (on any interface, which
may or may not be identical to the receiving interface).
