I do not agree about this.
Even though these frames are not going to be displayed, they definitely need to be decoded as a frame, stored and take up memory space of a frame in the decoded picture buffer as a reference frame for future frame decoding.
Even the requirement of Youtube mentions that the decoding frame rate can be higher than displaying frame rate, which implying that these "additional information" are exact frame(s).
Anyway, there is no point arguing about this, if your implementation can ignore the performance required to encode/decode these "additional information".
