While I mourn the practicality of the embedded jack on my iPhone 8, I've had quite a few headphones in a row whose jack ended up failing due to the way my phone is placed inside my pocket, and a repair was impossible, so that was quite an unexpected improvement to have the adapter possibly fail and be replaced at a very small cost instead of a full headset† going bust.
