I briefly tried a product called ExpertShield, a flexible screen protector. It started peeling off on the first moderately hot day. Before and since then, I've quite carelessly used my Fuji XE-1 without regard to the rear screen. Result: hundreds of tiny micro-scratches that are not visible when the screen is being used for viewing. I have more concern with a heavier camera body/lens that could make a more forceful impact if it collided with an immovable object. If the articulating sceeen can be easily replaced, I wouldn't bother with a protector.
