As a result of these observations, I am turning the question around:
Why would anyone want to use a 64 bit interface identifier?
I speculate that one possible reason for this was to design a SLAAC over
Ethernet that is reliable, simple, universal and straightforward to
implement.
In a way, I see SLAAC to have become so popular as opposed to DHCP.
Were DHCPv6 more developed we wouldn't have this IID-64bit problem, I think.
