Yes, but since the "benefit" is marginal, and not at all needed to solve the problem, it should not be considered part of the solution. Of course, if the non-zero-requirement is deemed positive for _other_ reasons, it's ok to "benefit" from it in this context too.

When the size is always non-zero (appearently not obviously) the rest of the code can be altered to benefit from that fact.
