Except the bolded isn't true at all, from what we've seen. Nothing from Star Fox, nothing from F-Zero, nothing from Wario, Fire Emblem, multiple retro and new series, and so on. Sure, "we haven't seen everything yet," but that excuse dies in a week, and not every series will have content hidden away everywhere we don't currently see it. Someone's getting the short end of the stick, and it's not Donkey Kong (at least in Smash Run), specifically its Rare era, even though "Kritters are irrelevant" is a ridiculously easy excuse to throw out as far as just using multiple Tiki variants and calling it a day, before adding in another dozen Uprising enemies.
Also, I don't understand why it's a Herculean task for people to consider, maybe, a "new" character didn't get in because they're "new," a reason Sakurai has never, ever advocated and has outright contradicted multiple times, but because they're unique, a reason Sakurai has gone out of his way to mention in the majority of interviews he does, they just didn't exist in 2005 or earlier for Brawl consideration.
