Those are standalone induction cooktops. It's common to install a cooktop on top of an oven by the same manufacturer. In that category, there are still many devices (from many manufactures, low and high end) with rotating knobs, integrated into the oven component.

well, maybe was common, with a bit of money and a new kitchen I would guess it is more common to separate the two entities and not have the oven on the floor... also very neat for the dishwasher if you have the space :-)

No, I think they are common and will be common for the foreseeable future even for most new construction, but I can't be bothered to find any references, which are unlikely to be publicly available anyway.
