Digital cameras: Speed limiter mode

In my opinion, one of the great improvements in digital cameras is Auto ISO. And not just changing the ISO with a fixed aperture and shutter speed. Modern Auto ISO controls the shutter speed (in P/A modes), slowing it down to a certain value before increasing the ISO. In modern cameras, the slowest shutter speed for Auto ISO is selected automatically according to the focal length of the lens, or can be set manually. And the ISO range can be limited.

However, I would like to see a shutter speed limiter mode in new cameras. It looks like the shutter speed priority mode (S, Tv) or the manual mode (M), where you can choose a shutter speed (and change it quickly). But the shutter speed you choose is the limit. If there is not enough light, the camera will use the selected speed and increase the ISO. If there is enough light, the camera will use the lowest ISO setting and the shutter speed will be faster than selected (this is the key difference).
