To add a note, administrators usually avoid *using* EUI-64 addresses for 
production, especially for their DNS records.
However, they often have an EUI-64 address because having default routes 
and other parameters automatically configured by accept_rtadv is convenient.
That's why I believe there will be an impact on servers. however, as you 
said, it's not an issue here.

At least, we use accept_rtadv in our production AND people typically 
configure their rtadvd with the autonomous bit. So this results in 
having EUI-64 addresses on the servers, which may be used in source 
selection.

I would like to kindly request @madpilot to create this patch for 
review, including a note in the UPDATING file, if everyone is in agreement.
