I do appreciate the simplicity (and effectiveness) of this wrapper, and I would definitely recommend this much simpler approach over a more robust tool in many situations. I think the added value (and increased complexity) from tools like this is that allow you to store your secrets not only on the filesystem, but also in various (typically external) vaults. Some also provide more granular access control to only a subset of secrets, revocation and so on.
