Different spec. If you want that to work, you'll have to either enable
IPv6 forwarding for the interfaces involved, or easier just add the /128
to the interface you really want it to exist on.

That it worked for IPv4 is IMHO still a mistake and might cause a
security breach. (take two links, one in secure net, other in public
net, if a host in the public one is compromised, just add a good enough
route and tada connectivity works. There is a sysctl flag for this
though afaik...)
