Can someone please explain what this means:

> up to now, [traffic predictions] [were] limited to Google Maps for Work customers only.

> Today [...] we’re making all traffic features in Directions API and Distance Matrix API available under our Standard Plan, and increasing the waypoint limit in Directions API for these developers from 8 to 23 waypoints. (Traffic features and higher waypoint limits in the JavaScript Maps API are available to Google Maps for Work customers for now.)

Does it mean that the new traffic predictions, as well as the increased waypoints limits, are not accessible via the JavaScript API except for Google Maps for Work customers, but they are accessible to the general public via some other API? What is the non-JavaScript Maps API?
