Hashes can change regularly due to metadata. Source checks may also require some filtration or preprocessing before comparison. Visual comparison is the best option here, especially if you have a complex document with multiple third-party components that may change both the hash and source but keep the visual appearance the same.

In this case, we indeed have multiple components (although not third-party), and being able to refactor those without risk is quite nice.
