I feel that the file is well documented enough and the methods it
exposes are also given enough context for the patch to be on its own.
Patch 5/5 adds a whole new feature to Patchwork which I feel should be
evaluated by itself. Without squashing, both patches can be more
self-contained. Ultimately, I feel that the following patch is more
than just a proof of concept, it's a new feature. This patch simply is
for healthier code as the module's functions will be used elsewhere
later.
