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.
