Three bindables are left which don't have this overriden due to them already not having a value-only constructor and not supporting `GetBoundCopy()` properly: - `BeatmapDifficultyCache.BindableStarDifficulty`. - `TotalScoreBindable` - `TotalScoreStringBindable` I could add support for them by passing the required data to them, as they seem to be able to have that shared, but I'm hesitant to support something which was already broken and never used, not sure.
