Narrowly scoped tests designed for specific compliance requirements are fine. They lower the barrier to entry to some degree for even getting testing and still, or often enough, return viable results. There's also SAAS companies that have emerged that effectively run a scripted analysis of cloud resources. The two together are more economical and still accomplish the goals that having compliance in the first place sets out.

When I was consulting architecture and code review were separate services with a very different rate from pentesting. Similar goals but far more expensive.
