I am no aware of any planned changes, but it does make sense as it really is a domestic business class service and not an F service. I did it both ways last month and was definitely F then.
The MH Golden Lounge (First Class section) has been really quiet every time I have been there. Food consists of a selection of about 4 or 5 hot dishes on a buffet. Last time through that included probably 2 or 3 traditional Malaysia dishes (a chicken, a beef and a vegie dish), chicken and mushroom pie (not what I expected to find there, but quite good) and I can't remember other options. The freshness depends on the busyness of the lounge at the time.
The drinks option is nothing special. Champers was ok, but not real top-shelf. They have a fridge full of ice cream
