That only covers a few basic repair types, the tooling is clunky (for a reason - those tools are designed to allow cheap-and-replaceable official employees to perform basic repairs to an Apple-acceptable quality) and the parts are hilariously overpriced. But it's considerably better than nothing. They also enabled a few repairs that were previously hard blocked by software, and required some incredibly complex hardware workarounds because of it - like FaceID replacement.

Make no mistake - I have zero faith in this being Apple actually trying to be better. It's much more likely that this was them walking back their "no third party repairs never ever" stance under pressure from consumer rights activists and regulators in places like EU. But it's a change for the better either way - and it would be good to see more of that in the future.
