Yes and no. First of all, I should make clear that there is absolutely nothing special about a recipe that says no resting is required. It is simply the author telling you not to do so. They are not guaranteeing that your macarons will not crack in the oven. This part is all up to you. I have a whole post on whether resting the macaron shell is necessary. If your batter is prepared correctly, it can go right into the oven without resting. Resting the macaron shell is great for those times when the batter is a bit thin and needs some time to develop a skin so it doesn't crack in the oven.
