We leave ours open, they don't have to be left wide open, just cracked open, I don't see the difficulty leaving a top load open vs a front load cracked open. You can't open a top load only part way because of gravity. But it only needs to be part way open to dry. My Father in Law has had his Maytag front load washer and dryer for 5-6 years leave the door cracked and it has never smelled, or needed to be serviced.
