It's useful to get "glue" code out of the way while building, but to the point in the article it all becomes very difficult to debug and maintain once there are problems in the that layer.

Spring Boot and other similar frameworks come to mind; by forcing huge amounts of indirection you lose a lot of visibility of your call stack because the convenient "glue" code is now orchestrating everything at runtime, but that code isn't yours, and it isn't easily inspected or fixed.
