The _good_ security people complain about deploying NAT in v4 or v6, because they don't think it is "security".

What sort of traction do you get with security people when you tell them NAT == "security in depth"?

If you mean "do people who get hired by $CORPORATION and do not know anything about security get upset when you tell them something they did not know?" The answer is "frequently, yes". I'm not sure what that has to do with the discussion at hand, though.
