Help wanted: this project goal needs a compiler developer to move forward.

• Key developments: @tgross35 got Inject compiler_builtins during postprocessing and ensure it is made private rust#135501 merged which improved which made progress on exported_private_dependencies lint only take effect in innermost dependency rust#119428, one of the two main blockers. In exported_private_dependencies lint only take effect in innermost dependency rust#119428, we've further discussed further designs and trade offs.
• Blockers: Further work on exported_private_dependencies lint only take effect in innermost dependency rust#119428 and Lint exported_private_dependencies misses public dependency via trait impl rust#71043
• Help wanted: T-compiler people to work on those above issues.

@epage hey i would like to help contribute with this, if you could probably mentor me in the right direction, i could learn and ramp up and move this forward, i could start with some tasks, scope them out into small bite sized chunks and contribute

This is mostly in the compiler atm and I'm not in a position to mentor or review compiler changes; my first compiler PR is being merged right now. I'm mostly on this from the Cargo side and overall coordination.

This is a continuing project goal, and the updates below this comment will be for the new period 2025h2
