Being clipped into road clipless pedals is the best for serious road riding and racing. Hence, they are called road pedals.
That said, nothing wrong with MTB pedals on a road bike; I have them on my gravel / allroad bike and they are great for commuting. On my road bike I have a set of Look clipless pedals and when I am commuting on it or riding with my daughter, I generally do it with whatever shoes I'm wearing, and clipless pedals really don't give you a lot of grip with your ordinary shoe.
It’s not worth getting worked up about.
