Having macaddr64 support both formats sounds nice, but how does it work?
Will we have to reserve one additional bit to select the representation?
That would make the type be 65 bits which is a clear loser IMO.

Is it allowed to just leave 16 bits as zeroes which would indicate that
the address is EUI48?  I wouldn't think so ...
