I think OP was specifically meaning a feature where you could see this stuff quickly and conveniently from ingame. Clearly nothing wrong with the idea - it's just making information more accessible (though I don't actually remember if exact wins/loses are available anymore).
Realistically this won't get implemented because it's just a cosmetic/QoL feature and if there even was substantial development being done to the game I imagine there'd be higher priorities. It's something that'd be totally doable with a lua script though.
