You'd be more likely to trust this document because it's shorter, worst case you could easily update or simply rewrite it if you found it to be grossly inaccurate, and because it deals with high-level concepts such as your system architecture which will change more slowly than the detailed minutiae contained in the larger document.

Or the team actually builds to spec, only to have your stakeholders say that's not really what they wanted.
