Elytra should stop working right before breaking as a warning.

I have seen many posts about how you should have a visible durability bar for the elytra during gameplay. It is obvious why this has never and will never be implemented into the game. At the same time it would be great if we had some form of warning so you don't randomly fall out of the sky. My idea was when the elytra gets low on durability when you are flying, it starts shaking or rippling or something. Something visible that would give the player a warning. This wouldn't be too obvious but definitely wouldn't go unnoticed.
