4.20 Rect Light falloff?

Been toying with the new Rectangle lights in 4.20 - the one thing I’m really missing with them is some kind of falloff control.

There is no “Inverse Squared Falloff” bool, nor any exponent to play with - I’m guessing that’s been done on purpose, but I’m just wondering what the reasoning is - is it an optimisation? Is there a possibility of getting some kind of falloff control in future? Even scaling the radius quite large doesn’t affect the light’s influence as I expect, so I’m finding myself reverting back to spotlights.

@Spoondog they have changed a lot of lighting features in 4.20, it would be great from UE4 team to have a live stream to showcase the replaced the options and some of the new features
