Mattia, can you list any relatively large websites using this approach? It seems to me it combines the cons of adaptive and responsive approaches without retaining any pros, but maybe if I could see it working I'd believe :)
Twitter, Facebook and Github. They are both adaptive to serve different experiences, but both experiences are also responsive.
Contactlab.com for example use this approach in its data-heavy applications. The main core experience is on desktops but some apps are accessible even on mobile as a "light" version. So instead to just use mq to hide functionalities or ui elements they provide two experiences, both optimised without compromising each other.
