I'll use this issue to track reviewing all usage of bytes types to see if they should be changed following #9001 and PEP 688. The below list is from git grep -c '\bbytes\b'.
My plan is to do look at each file one by one, reviewing bytes occurrences. I'll generally assume occurrences in return types or IO[bytes] are correct, but check occurrences in argument types to see if they should be ReadableBuffer, bytes, or similar.
