Create Fitted Artboards from layers?

While I think this is possible ( not actually tried this out ) it would only make sence to do… if each layer's art does not over lap in any way?

#target illustrator
main();
function main() {
  
          if ( app.documents.length == 0 ) { return; }
          var doc = app.activeDocument;
  
          doc.layers[0].hasSelectedArtwork = true;
  
          doc.fitArtboardToSelectedArt( 0 );
  
          doc.selection = null;
          for ( var  i = 1; i < doc.layers.length; i++ ) {
  
                    doc.artboards.add( [0,0,72,-72] );
  
                    doc.layers.hasSelectedArtwork = true;
  
                    doc.fitArtboardToSelectedArt( i );
  
                    doc.selection = null;
          };
};
