Lubliner: No Tefilin until the K’vura is a Din of Aninus. It also isn’t worn on the first day of Aveilus (maybe they put it on at Mincha, I’m not sure about that; but definitely not at Shacharis).
Wallflower: The Mechaber Paskens that an undisputed Gadol HaDor has the Din of a Rav Muvhak, for whom you tear Kriya. An undisputed Gadol HaDor is incredibly rare nowadays (indeed, R’ Elyashiv probably didn’t qualify because not all Poskim were Kafuf to him), but R’ Ovadia almost certainly qualified as one for the Sephardic community.
