Is there a good reason why you have to set the light intensity manually when <- -> Cycles/Eevee?

My question was and still is, when we set the color to white and before we enable use node and increase the intensity, what is the real world watt equivalent of that default strength ?

A year ago I thought of course there were real-world equivalents to lighting in 3D . . .
