I had a moment recently where I was trying to understand "why developers would create such an interface" in an application I was using when I realized I was looking at, basically, a "React-type interface" in a place where that doesn't fit, and the "why" is perhaps that this is the kind of thing younger developers are used to seeing/implementing, so they probably don't even recognize when it's a bad approach.
