One of the reasons I stick with VTNZ is to have a thorough inspection and early warning of any potentially dangerous developments.
I may not like things that they find, and I sure as hell hate paying for repairs, but at least I know about them and fixing them becomes a priority.
I also attribute considerable value to their professional judgement (to label it an "opinion" IMHO is harsh). Because they don't do repairs they have no incentive to signal unnecessary work.
