It would be very useful to have OnDestroy for situations where a rendertexture is created on Awake or Start in a graph, and you’d want to destroy the rendertexture to free up memory, but you wouldn’t want to do it on Disable, as you’d have to make sure the rendertexture was created in OnEnable, which might not be preferential. OnDestroy would be a great compliment to OnStart and OnAwake!
