Apple has a long history of working against right to repair and third party repair shops. This includes making it difficult for third parties to source the parts needed and changing the designs to requiring part pairing in the name of security. It got to the point where repair shops were buying broken Apple products so they could hopefully source the parts needed.

Looking through what they provided now, it's basic stuff any third party repair shop could do if they could source the parts. It's useful. However good electronic technicians can go beyond that and do board level repairs. But that requires schematics and diagrams. A lot of times they would have to get those through other parties who in turn got them through less than official means or violated NDAs.

Guess what Apple isn't providing? Board level information. This is just doing the minimum the law requires them to do.
