The components are a concern of the engine and the game code, not of the editor. There is nothing preventing components from talking to each other when a generic editor is used. Have you ever played with Unity? Their modular design is generic enough to allow different components to be connected to each other.
Not to mention that interconnection between components is often also achieved via code inside each component (example: gameObject.GetComponent() in Unity), which is not really the concern of the editor, but rather of the engine and the game code.

I really don't see what "bunch of libs glued together" has to do with my comments at all. Are you sure you answered to the right person? Are you answering to the article in general?
