Me, too, trying to avoid that to maintain a polished/finished look. I also like the slatted side so if I am drying dishes it allows air to get through.
CHANGES: I kept looking and that sink cover is one of several changes to the 2019 fall model of the 2104s. FR eliminated one of the slide windows and put a cabinet there (I prefer the window) but they also changed the oven to one that appears larger, has traditional knobs and a glass front oven door that looks residential (beautiful), they traded out the acrylic double sink for stainless steel (nice), put that new cover on top. For some reason the shower head is mounted on the opposite side of the shower and wow, almost forgot, they now have the one piece ladder type step that folds up straight inside the door when in transit.
