I'm not sure I agree with this... specifying interface + IPv4/v6 NH on
some platforms can be useful specifically to stop recursion when the
interface goes down by for a nexthop that otherwise may recurse (often
to an aggregate or default).  Whether it's required to program static
routes in i2rs I don't know, but if we plan to support it, a way to
stop undesired recursion would be useful.
