I would love to have this,
But, in reality this would get fucking ridiculously huge, since there's alot of players who upload replays pretty much every day, or such like me that make like 50 wip replays each day scrapping like 40 of them or so,
In whatever sense, i would love for this to be a thing, but i'd probably go with what deak said,
Not supported unless it won't take up disc space
