If I remember correctly, 343 said that the reason the CSR won’t be visible in game is because they don’t want boosters and de-rankers in H4 like in H3 (although people told me that there weren’t a lot of them in H3).
A simple solution would be to implement an in-game reporting system so that we’d be able to report boosters/cheaters/de-rankers/whatever. That way, we could have a visible ranking system.
