Honestly I prefer to think of it as a branch, rather than a fork.
I am curious if you've got anywhere with this?
I just saw kernel commit e0056593b61253f1a8a9941dacda22e73b963cdc
ip_tunnel: fix ip_tunnel_lookup

actually, not a /60, but it is requesting a /60 and thus distributing
a source specific route to that /60.
