Sorry, Ricky. But that won't work. EUI-64 is required for autoconfig,
and it expands the 48 bits to 64 bits by inserting FFFF or FFFE
depending on if the original is a MAC-48 or EUI-48 identifier.

I'm rather puzzled why this blatant layering violation is still sold
as a must-have feature.


It's not a must have if you manage your own network. There are always other options. That being said, if you are an ISP handing out prefixes to customers, there is an expectation that the customer will probably use it given the direction CPE implementations are going. Thus you have to predict that if you don't want to setup all your customer's networks for them, they'll probably be using /64 per subnet.
