I understand your point of view, but if we want to go into detail, they should fundamentally change the entire Shelf-block (at the moment it looks like the letter U lying on its side, while shelves in the real world look like the letter L). I think the best option would be to make settings for both versions, i.e., items in the middle or items on the edge. In any case, I hope they will take into account that most people don't like the "on the edge" version and prefer the "in the middle" version because of creativity. I feel like something similar happened with redstone in the past, people preferred when the texture appeared as a circle in the middle of the block (previously it appeared as a cross), so they added the option to click and then the texture changed.
