The extra bookkeeping it presents shouldn't exist, period; notions/implementations of scarcity and (inordinate?) empowerment are for the DM and the DM alone to decide.
It's really no book-keeping at all... and compared to the book-keeping of working our which bonuses from which items stacked or did not stack with various bonuses from other items, that was the staple of 3.5, it's laughable that anyone would actually complain about it in good faith ^.^
