When I checked in there was no "small card with Diamond benefits". So if they are changing the rules, that would be interesting.
This is a new report from just a few days ago:

The F&B credit for Diamond members FAQ has this to say - emphasis mine:
When selected as a MyWay Benefit by Gold or Diamond Members, a daily Food & Beverage credit equal to the value shown in the table below is provided for the Member and up to one additional guest registered to the same room each day of Member's stay.
The Food & Beverage credit may only be used in the hotel's designated restaurant(s) or Executive Lounge.
