Viewing Champion Mastery on Summoner Profile

I was just wondering... wouldn't it be great if you could see the masteries of all of someone's champions on their profile? As it is now, you can only view whichever three you mastered/have the most points in, and then all the in-progress ones, but none of the other champions that you have level five mastery on aside from the three on the front page.

Wouldn't it be better to have a tab or place where you can view all of someone's champion masteries? Or only the level 5 mastery champions. I mean, champion mastery is ultimately mostly for show anyways, so I think that'd be a pretty cool addition to implement. For people who don't want people viewing their masteries, there could even be an option to keep your mastery section hidden or w/e.
