No, I don't need to know the exact details of the engine. Your cars manual probably does not list the exact engine timings either. It says "fill in diesel here." If I want to tune my car I read the workshop manual, not the user manual. I totally support that the workshop manual exists, but git is lacking a users manual. I can explain my tester to run automatic tests, I can teach them git, but if I point any of them at the gut manual, I get a blank stars. It technobabble to them.
