Only people who feel comfortable repairing their own devices will do it. Most will just drop their devices off at the Apple Store or a third party repair service like Louis Rossmann. R2R legislation will most likely make it easy for 3rd party repair shops to get parts and repair resources, not individual consumers.To me one major problem is that untrained, poorly trained, or random users can damage sensitive components then try to claim it was defective. Or cause an issue that burns down their house or blows up the battery 🔋. These are not copper tops. Even with training there have been battery explosions at Apple stores during repairs.
