It was never banned to begin with. No version of the ruleset has ever had any infinite banned, ever.
It doesn't matter if Luigi has won tournaments or not. It's not even about that. It's about not being arbitrary. There's no reason to ban DeDeDe's infinite on Luigi, or Donkey Kong's infinite on Lucas/Ness, when the Ice Climbers can infinite any character in the game.
Furthermore, D3's "infinite" on Luigi isn't even an infinite. It doesn't become infinite until around 120%. Before that Luigi can wiggle out. This is true for Samus and Mario as well. If you would like more information on that, feel free to ask.
Either you ban all infinites or you ban none. How "hard they are to perform" isn't part of the equation. They are either broken or they aren't.
If you have a problem with being infinited as a certain character, you have the option to counterpick and use another character.
