That's a refreshing development. Some formerly staunch advocates of owning multiple lenses, each with it's own built in "rendering" filter, are now starting to warm up to the idea that you can be equally arteestec through using one (good) lens and multiple filters. In a decade or so they might even look into sunstar filters 
The point is this is not a development (refreshing or not). Diffusion filters have been around for decades. They are a way to alter the rendering of a lens but they have their down sides too. Neither is it possible to get every type of rendering with filters. And certainly one lens with filters will not give you exactly the same capabilities of multiple lenses. Diffusion filters for one thing always affect light transmission and the amount of light hitting the sensor, so in low light will have their limits. They are typically best with a strong light source in the frame, but they can really fail in such situations sometimes too. Neither are they cheap, so sometimes having a second or third lens can be just as cheap as multiple diffusion filters. They are a useful tool, but not without their drawbacks. In general, I think they are more useful than star filters, which I suspect you know have also been around for decades, but I have never seen a star filter from which I like the sunstars, but YMMV.
