Any way to use "Editor Apply Spline" on Non-Destructive Landscape Layers?

Hey everybody,

Playing with “Editor Apply Spline” node, I was surprise that it didn’t seem to work with Non-Destructive Landscape Layers.
Is it just me? (I’m a bit lazy to jump to the source code once again to figure this out :P)

Not able to check the source codes of anything, but can confirm that turning landscape layers on in project disables Editor Apply Spline node.
And it feels wrong.
Filled a bug form, but i suppose Epic wouldn’t agreee that this is a bug.
So made a feature request post also
