Typically it would be a policy not to introduce new attributes which are not yet used, and add the other attributes once a user appears. However, I think it makes sense to have the full set of desired attributes especially given the ioctl interface limitations which would otherwise require a lot of reserved space or new ioctl numbers. Especially given the uAPI here has been discussed and changed heavily from previous patch iterations.
