>I was surprised by the number of test pads exposed on the Coin - all those small metallic squares are programing points / test points. This suggests to me that Coin is still going though some debugging since it’s rare to see so many pads still exposed on a shipping product.

Perhaps their tester just couldn't probe the smaller pads/components. In general, any shipping product these days is going to have a significant number of test points, it is just that they are often not explicit.
