To my knowledge, PCM over S/PDIF is limited to stereo. The channel 
numbers where probably meant to transport a quadraphonic or surround 
signal over _multiple_ cables. This would untie the audio channels from 
the cables, thus adding flexibility.

BTW: MPEG is a nono as well. Their are an astonishing high number of 
installations, which support Dolby Digital Surround, but MPEG Stereo 
only. DTS is not available anywhere, too (and we can't encode it anyway 
;-)
