I think if it was any harder than "flimsy" (on a scale from flimsy to unbendable), the stress angle would happen at the end of the stress relief part, which would be the same thing as not having the stress relief part. So, I think there needs to be some compromise that leverages the durability of the old model, but the design of the new model (I think it's better to have a more functionally-durable product, than design-durable product)
