I actually think it would be out of scope for an ARP RFC to specify this
(and none I'm aware of do). It really is an IP layer decision. That
is, the decision naturally extends beyond the scope of ARP, applying
also to layer 2 devices which don't even do ARP.

Depends on whether you run your interfaces in promiscuous mode, and send
frames with different MAC addresses from one interface. ;-)
