What happened to the "direction" and "accuracy" properties in API v4?

Hi!

In API v3, the “map_features” API response had “direction” and “accuracy” properties:

{
  "type": "Feature",
  "properties": {
    "accuracy": 2.4432428,
    "altitude": 53.205185,
    "detections": [
      ...
    ],
    "direction": 41.288395,
    "first_seen_at": "2019-12-16T18:18:37.174Z",
    "key": "039xnlx3tpkeebhtwf6bso1jaf",
    "last_seen_at": "2019-12-16T18:18:41.184Z",
    "layer": "trafficsigns",
    "value": "regulatory--no-left-turn--g1"
  },
  "geometry": {
    "coordinates": [
      -122.43625095994653,
      37.762075472228574
    ],
    "type": "Point"
  }
}

I wonder how I can get these properties using API v4 or how to calculate them?

Wondering the same. Will these attributes be available in V4?
