Why?  All you need to send Hellos is a destination address and an
interface.  If you have a point to point link, then you know your
neighbor's address - either from configuration or from routing
protocols.

If the interface is a broadcast-type interface, then you would obviously
need some other mechanism to learn the neighbor address(es).  If you
know them, however, there is no reason why you couldn't send Hellos as
well.
