flash – Why can’t HSS mode be automatically turned on for shutter speeds faster than the max speed sync?

When you have a flash system attached to your camera, you cannot shoot faster than your maximum speed sync (which usually is 1/200s or 1/250s in most models). If you need to go faster, then you have to turn on the HSS mode on your flash.

Having a background in IT, I have always wondered why nobody has made a camera that automatically sends a signal to the flash in order to turn on the HSS when the shutter speed is faster than the camera max speed sync.

Is this a conscious decision that manufacturers have made not to include such feature, so that photographers can be aware of the HSS flash power limitations?
