Ovens on cooker ccts

In domestic kitchens, what do you think of the practice of connecting ovens to 32/40A cb cooker ccts via dual cooker connection outlet plates? For example, along with a 6kw hob, a 2.5kw oven is connected via a 1.5mm2 3 core h/r flex? One view is that it's acceptable because the flex can't be overloaded and the cb provides s/c protection for the flex, nor would it be coded on an eicr.
