I understand that. But, in real life, a rating of zero is different from the absence of rating. For instance, in a number-based school grading system, handing in a blank copy gets you a zero; not passing the exam because you’re sick gets you no rating.
I know it’s become customary for commercial websites, for instance, to not allow a true zero rating. But other usages (or other choices for this use case) do exist.
I just want to be able to give a rating of zero. Currently, the minimum is one; we should be able to decide that the minimum may be zero.
For instance, if I want to rate dishes, the rating for what I don’t like at all should be zero. A rating of one means “a little”.
