ReadOnly JSDoc Tag Not Enforced in JSON Serialization

[RueDeRennes]

The items property (which is a property in my WebComponent class) is annotated with the @readonly JSDoc tag but is still serialized without the readonly modifier afterwards in the JSON file. I’m using the --format json2 flag.
Is there any other way to make the read-only modifier available in the JSON file?

// ......

/**
 * Gets or sets the `items` property.
 *
 * @public
 * @readonly <- it should be readonly but is missing in the generated json file.
 */
public get items(): Array<HTMLElement> {
    return this._slot?.assignedElements() as Array<HTMLElement> ?? [];
}
