The bottom line here IMO is that EIGRP adj/hellos always work via
multicast, regardless if you have neighbor statement or not. And it is
not connected to split horizon in any way, this comes into play later
when actual updates are sent.
So attention must be paid especially to NBMA configured for multicast.
Please correct me if I am mistaken here.
