You always need it. It is part of ABI compatability, if you declare that a struct can be extended then you have to check that someone isn't using a new extension with an old kernel. Globally we define that as meaning the unknown part of the struct is 0. If this is a problem for your API then you are probably not designing it properly for extension.. I actually don't expect MIN_SZ to be used very often.
