Mariyung trains consist data / short platforms

With the introduction of the Mariyung fleet, and in particular the 6 car variants, it would be great to know where specific amenities are located along the train (e.g. bike racks, luggage storage, accessible toilets, etc). I can see the GTFS extension file has these listed under CarriageDescriptor:

message CarriageDescriptor {
  optional string name = 1; 
  required int32 position_in_consist=2;
  enum OccupancyStatus {
	EMPTY = 0;
	MANY_SEATS_AVAILABLE = 1;
	FEW_SEATS_AVAILABLE = 2;
	STANDING_ROOM_ONLY = 3;
	CRUSHED_STANDING_ROOM_ONLY = 4;
	FULL = 5;
  }
  optional OccupancyStatus occupancy_status = 3;
  optional bool quiet_carriage = 4 [default = false];
  enum ToiletStatus {
	NONE = 0;
 	NORMAL = 1;
	ACCESSIBLE = 2;
	}
  optional ToiletStatus toilet = 5;
  optional bool luggage_rack = 6 [default = false];
  optional OccupancyStatus departure_occupancy_status = 7;
  
  extensions 1000 to 1999;
}

but the data is not yet being presented in the API.

Is there a rough timeframe for when we can expect the data to become available?

On-board the trains know where these things are, but it would be great to know ahead of time to plan for short platforms, or when you can’t run to the right carriage as the train is already pulling in. At the moment if you guess wrong, you could be up for a 60+ metre dash to the correct spot on the train (happened to me yesterday).
