Regarding the specific instrument shown in the picture, I had the opportunity to visit the Accordion Gallery in person and tried one with that bass register switch design. Neat in theory, but my brief trial found it annoying to work with. In the end, a single button for each register without the overhanging levers seems to work better.
That bass register switch design is very typical for Scandalli. Like you I didnt like it (the one time I tried one).
