Load factor in the October update on Europe flights was down to 74.2% - lower than any segment of their long haul network.

A flight doesn't necessarily have to be 100% full for this to be necessary, or a good idea (from the pont of view of the airline). Many other airlines manage just fine without a "wardrobe" and all KLM really needs on its shorthaul network is a place to store the trolleys, not a "galley".
