Completely agree. Had hoped with iPhone X they would move to have interactions at the bottom, since constantly involving reachability (which is now disabled by default) to go to the top menus (since not all apps allow you to swipe from the left to go back consistently). Several apps like Instapaper work great the main navigation actions in the bottom. They have items in the top but those are ones you won't need to access often. And they leave space at the bottom to not interfere with the home button line area. Maybe we will see a push to this UI direction from Apple officially in iOS12 as I imagine iPhone screens will only get larger.
