Descriptive repeater rows - how?

It’s working for me with the current stable version if the display attribute is directly put into the field object:

{
  "field": {
    "type": "set",
    "display": "bp_title",
    "name": "best_practice",
    "label": "Best Practice",
    "options": {
      "fields": [
        {
          "name": "bp_title",
          "type": "text",
          "label": "Title"
        },
        {
          "name": "bp_desc",
          "type": "wysiwyg",
          "label": "Description"
        }
      ]
    }
  }
}
