I am leaning towards removing it. But I might keep it also.
Trying to simplify and build a "Unified Field Theory" as it were. Needed, no. Fun tinkering, kinda?
In our games since the first manual of the planes, we had places where the ethereal bleed onto reality. You could walk into the mists, go ghostly, look around unseen, etc. If you wandered deeper, you get get lost, and end up in the Shadow Plane, or the "Bright" (the Faerie Realm).
Now if I remove the ethereal, there's no "wandering". You are either in the material, or in the shadow plane. Poof. So the BORDER ethereal is what we used the most. I can indeed do without the deep per se, although if you wander around lost in fog until you accidently step into faerie, or shadow, or Ravenloft, what else would you call the area you traversed?
I make the ethereal the same thing as the Weave of magic. It is a natural psychosensitive telekinetic force, relating to force, soul, and is the fifth element. The other four elements are made out of ether. It is the fundament of all magic.
So, the ethereal plane is the same thing as the "spirit world", and includes both Fey (infused by the plane of positivity) and Shadow (unraveled by negativity).
In the shallow ethereal, spirits can interact with the material world.
The deep ethereal is the Fey, Shadow, and Four Elemental planes, respectively, depending on frequency.
