If people are really concerned about this, we can always add a DHCPv6

able to receive other configuration parameters even if you're not

to give me any addresses." Thus, the old servers would ignore this
option and new servers would know that it is OK to do this.
DHCPv6 is not a full standard. I don't think it's widely deployed
at this point. I would rather take the risk, as you suggest, than
add an extra protocol to negotiate whether we can do this - it's
extra logic in the server that will be needed for zero clients two
years from now - just another piece of unused code that could be
buggy, because it's never used, and thus could be an avenue of attack
for some enterprising young script kiddie.
The time to get conservative about breaking clients by sending them
unexpected responses will come, but it hasn't come yet, IMHO. I
haven't heard anything to contradict this - has anyone else?
