What's the point of exporting these separately when they are the same as
the enhancement AVStream's dimensions?

The enhancement stream is of data type, so width/height are undefined in it. Hence including these here.

      AV_STREAM_GROUP_PARAMS_IAMF_AUDIO_ELEMENT,
      AV_STREAM_GROUP_PARAMS_IAMF_MIX_PRESENTATION,
      AV_STREAM_GROUP_PARAMS_TILE_GRID,
+    AV_STREAM_GROUP_PARAMS_LCEVC,

This seems like it could use some documentation.

Yes, will add something.
