I wonder if this is getting close to the actual reason. That is, there's a "latent space" of composable units that, say, have blurred edges (or something) for easy combination that ends up looking like an airbrush/glossy effect. I think this idea is quantifiable and testable. It'd be interesting to see if this, or something like it, is the actual reason.
