Yes it is useful for other checks, but the code here is specialized for this problem only. It is possible to make a call graph that stores the "parents" of the calls, probably root items that are of a special kind, and can add notes for call chain. But there is already a `clang::CallGraph` that can compute call graph, if I remember correctly it was not usable here because the parent node (caller) is not available. That `CallGraph` could be extended too.
