Ah yeah, isn't that the definition of something you don't directly depend on? Of course they "could just replace the OS", I can also just write a new web browser and use it to browse the web as it's supposedly a standard. Except neither will support even a fraction of the originals' capabilities, at much worse performance and millions of incompatibilities at every corner.
