I believe the concern regarding standardizing the methods for locating debug information files is valid. Based on my experience, the only reliable approach to achieving this is either documenting it in a well-agreed spec, document, or website, or enforcing all symbolication tools to utilize a shared implementation. Microsoft employs the latter approach by mandating that all tools (such as Windbg, Microsoft Visual Studio debugger, Sysinternals tools, UMDH, etc.) share/use msdia.dll for symbolication. 

Additionally, as I mentioned in previous inline comments, the most useful feature for these symbolication tools is detailed symbol search paths logging/callbacks, which enable users to self-discover the implementation rules. In my opinion, improving in this direction is much more useful than enforcing consistent implementations across all tools, and it is also cheaper/easier to achieve. If a user can figure out through logging where their dwp/debuginfo/dSYM files are being searched by the debugger/tools, they are happy to self-fix the issue without concern for the implementation/consistency.

Since there is currently no standard/official documentation yet, I will accept the patch to unblock the customers. Feel free to continue the discussion and improve the experience for users.
