Let's remember that ethernet is by nature a broadcast medium and if you want it to behave like a point-to-point link you will have to be careful. Adding static arp entries has some drawbacks which you do not have on real point-to-point links. In the end you are still trying to let a broadcast medium behave like a point-to-point link. Nothing more and nothing less.
