You can extract materia out of it, which resets spiritbond back to 1%. There's no reason to ever NOT do it when you see items at 100% and even your inventory thing shows the items with 100% spiritbond as white, not green as reminder to extract it. You dont lose anything and there are no advantages to having higher spiritbond. And highest-tier materia from current high-level gear can sell on MB pretty well, as well as some tier-1 combat materia.
