I don't understand what would be accomplished here except, possibly, for relabeling terms. "Now we're going to call it fermionic spirit, not just fermions, but it still obeys the Pauli exclusion principle."

It seems roughly as effectual as painting particles with gender, or talking about how angry a ballistic trajectory is. Motion exists and is perpetuated by fury, which just happens to follow Newton's laws to a very good approximation at conventional scales, and special or general relativity at other scales. I've accomplished...what? Made physics more exciting because it's now an "anger vector" not a "momentum vector", I guess? But was I even making any claim at all, except about how better to amuse ourselves with language?

That is: if there is no conceivable observation we could make that would help us distinguish the two views, is it actually a different view or just different pronunciation of the same view? ("I call it toe-may-toe, you call it tah-mah-toh.")
