Astronomers may have found giant alien 'megastructures' orbiting star near the Milky

Isn't a gradual dimming of 20% over a century exactly what you would expect from a dyson swarm/matrioshka brain construction? Assuming linear construction this would result in a 500year construction time which sounds perfectly reasonable for me given self-replicating nanotech for example.
For the missing infrared - wouldn't a matrioshka node produce only radiation close to the temperature of the cosmic background radiation because every next layer would utilize the waste radiation of the previous one? Has anyone done the math on that?
