I'm aware, yes
I did consider that fact while writing my response
I should also note that Kaladin mentions that a group of Fused also use Lightweaving, similar to how Shallan does, in RoW ch 2 Severed Cords¹. Although post-OB many theorised that the usage of the Surges shown by the Fused isn't Voidbinding, it is the only example we have of Odium-aligned magic, regardless of whether it's Voidbinding or not, and it seems, from Kaladin's comment, that they cast illusions, not light. I also included a WoB that indicates that using Illumination to manipulate EM waves might be possible, which makes sense because that's what illusions are, precise manipulation of photons to trick one's vision.
