If I understand correctly, this option entirely prevents picking up items during an attack. While this may be good for preventing accidental item pickups, I fear that this option may be strictly worse than not using it in 99.9% of cases, since certain combo routes may be impossible, catching an item while throwing out a hitbox is a very useful utility, and accidentally catching an item is a very common way to save yourself from getting hit by it.
To fix this, I suggest making it so you can still grab items during attack startup, but only if you hit the grab button as if you were going to do a regular Z-catch.
