Would it be in any way beneficial to shield each individual wire in twisted pair cabling?

So there is F/UTP, which has an outer, single layer of foil. There's U/FTP which has foil around each pair. There's F/FTP which combines both. However, would it be beneficial to foil each individual wire?

I assume the answer is no, as this type of twisted pair cabling barely exists if at all, but im curious. Wether the answer is yes or no, why is it that way?
