If it's just casting, then fixing an unexploitable casting bug is tidier than leaving it,
explicitly states intention, and prevents these souped-up aggressive optimizing compilers used
on the kernel from optimizing in a problem sometime down the road. On the other hand,
unnecessary changes introduce risks of adding as many problems as they fix.
