The ability to request and return a subset of the fields seems useful regardless and it can be used to avoid the need for this kind of padding. A sufficient amount of padding wouldn't be too bad either, but I guess we should not have both the padding _and_ the option for extending the structure after the padding. With the padding, the 'size' argument can go away, though I'd argue that even without the padding we can safely add extra fixed-length fields when needed and not need a size argument.
