One problem tools like these tend to have, to take Amplify as an example, is that they turn what might be a complicated problem served by heterogeneous tools and glue code into a very narrow happy path solution and dragons in all other directions. When the problem is handled piecemeal, the dragons are local to whatever specific problem areas exist; when the problem is centralized, the dragons are everywhere.
