Discord logging

Hey, I have a suggestion. I already did one but I don't think anyone seen in so I thought about redoing it. I was wondering if a Pfp, Username, And friend/unfiend feature and server join and leave history will be put in. The reason why is because it will help people to not forgot someone when they change there profile and they may unadd them. I think it would improve discord ALOT. What do you think?
