In the first example (Clubhouse), it's a deliberate design decision to show the edge of the cards on the left as an affordance that you can swipe to get back to the main content.

The Google Maps example is probably because most people want to see the list of results when you search for a category of businesses - the map is secondary. If you do want to see more map, you can just pull down on that handle at the top of the list or press the "View Larger Map" button.

Many of the other examples seem somewhat nitpicky, so I don't really think this supports the argument that nobody is designing for small devices.
