If someone was using RDRAND16 to seed a PRNG, choosing to omit one single value (a zero) from the return value would not significantly improve the generated values, if at all.
Looked at another way; leaving out the zero also dosn't significantly hurt. If the is any risk if it breaking the PRNG why take the risk.
