arent there more than just apch / apcn isom tags?

libavformat/isom.c lists a few:

{ AV_CODEC_ID_PRORES, MKTAG('a', 'p', 'c', 'h') }, /* Apple ProRes 422 High Quality */
{ AV_CODEC_ID_PRORES, MKTAG('a', 'p', 'c', 'n') }, /* Apple ProRes 422 Standard Definition */
    { AV_CODEC_ID_PRORES, MKTAG('a', 'p', 'c', 's') }, /* Apple ProRes 422 LT */
    { AV_CODEC_ID_PRORES, MKTAG('a', 'p', 'c', 'o') }, /* Apple ProRes 422 Proxy */
    { AV_CODEC_ID_PRORES, MKTAG('a', 'p', '4', 'h') }, /* Apple ProRes 4444 */
    { AV_CODEC_ID_PRORES, MKTAG('a', 'p', '4', 'x') }, /* Apple ProRes 4444 XQ */


shouldnt these other 4 tags also be added?
