How would you use them to assign MAC addresses to multiple interfaces? The nvmem-cells property in the network device's node can only refer to one cell, and not to i.e the cells value + 1. I think it would be useful to have a way to express this setup for systems with many interfaces, but am unsure of where this should be described. Maybe a "mac- address-offset" property in the generic ethernet controller binding?
