True, although I think that's pretty much unavoidable given the design
of ipv6 though (isn't ::1 always the router for the subnet)?  You
could always honeypot or Turing pit the other 2^16-(n) subnets if
you're really paranoid about someone finding your router without a
valid IPv6 address to start guessing with.

The source code also seems to support using
dhcp-range=::,constructor=*,ra-names,ra-stateless (etc.).  I'm not
sure what dropping the "1" does, exactly, not having perfect ipv6-foo
skills yet.
