Yeah, you’re putting the effects first, which seems fine so long as you always add the effects (you’re right in that there seem to be some optional fields, so I’d be wary about moving it further down); updating the comment to reflect where the effects are encoded is a good idea—I didn’t notice that at first because the diff didn’t include that part of the comment.
