Villager with raid results

Wouldn't it be useful if there were a villager who documented your results for a raid, such as enemies killed and villager casualties? I think it would make raids and such a bit better, a villager that can sell books for a limited time (as long as the hero of village effect lasts maybe) that tells you what you did. The book could tell you what enemies you killed, what villagers died, how many players were defeated (and at what wave), how many emeralds you collected, how many waves there were and so on. This would be a pretty cool and useful feature, not sure if this would be for a new villager or an already existing feature, the only problem would be what happens when the villager died during a raid...
