 		 * Enables filtering the mime type used to save images. By default,
 		 * the mapping array is empty, so the mime type matches the source image.
 		 *
-		 * This should be considered experimental as there are a few edge cases that
-		 * still need to be solved.
-		 *
-		 * When this filter is used in combination with the {@see 'wp_editor_set_quality'}
-		 * filter, the image quality value used will be that of the original mime type,
-		 * not the mapped one. This could result in unexpected image quality for generated
-		 * images. See https://core.trac.wordpress.org/ticket/53667 for more details.
-		 *
-		 * When a mime type is mapped to another, and two images with the same name are
-		 * uploaded (image.jpg and image.webp, for example), the generated images for one
-		 * will potentially overwrite the other's.
