And then people will scream because someone setup a layout that

There is that chance yes especially from access networks which use RA.
As this thread has drifted off topic any way, would it for instance be
a good idea to simply not accept mail from hosts that clearly use
autoconfig ie reject all smtp from EUI-64 addresses. Of course not a
wise idea for your own outbound relays which should handle mail from
your customers but on the incoming side it might as well save a lot of
headache and there is no need to keep track of which /64 are access
networks.
Just a few cents,
