+
+Importantly, this module's public API exposes a way to read this metadata, but
+not to alter it. This is read-only information!
+
+If we find ourselves using any particular piece of metadata often,
+for example `title`, we could expose a convenience function like this:
+
+Article.title : Article a -> String
+
+If you like, it's totally reasonable to expose a function like that for every one
+of these fields!
+
+(Okay, to be completely honest, exposing one function per field is how I prefer
+to do it, and that's how I originally wrote this module. However, I'm aware that
+this code base has become a common reference point for beginners, and I think it
+is _extremely important_ that slapping some "getters and setters" on a record
+does not become a habit for anyone who is getting started with Elm. The whole
+point of making the Article type opaque is to create guarantees through
+_selectively choosing boundaries_ around it. If you aren't selective about
+where those boundaries are, and instead expose a "getter and setter" for every
+field in the record, the result is an API with no more guarantees than if you'd
+exposed the entire record directly! It is so important to me that beginners not
+fall into the terrible "getters and setters" trap that I've exposed this
+Metadata record instead of exposing a single function for each of its fields,
+as I did originally. This record is not a bad way to do it, by any means,
+but if this seems at odds with <https://youtu.be/x1FU3e0sT1I> - now you know why!
