I think their "just" is saying this option should be on by default & mostly hidden

  Indeed, I am pretty sure this is how Photoshop has worked under the hood since forever. No point in persisting a sparse layer.

  That's not how I read it. The fact that layers have boundaries shows up all over the place in GIMP, turning on "auto expand layers" in the brush tools by default wouldn't do that much to "get rid of layer boundaries".
