Because enum allows the potential values to be restricted to a set of
distinct values rather than a range. And while yes, I understand that
the value can be validated, or the step can in this case be set to
correspond to the difference between the current 2 values, this approach
would neither make it clear to the user what the permitted values are,
nor would it scale well once additional values are required.
