The new name better represents the actual meaning of the value. "hide_value" was wrong because it didn't even hide the label in many cases. This property just indicates that the input is still understandable even if the label is not drawn. It's up to the drawing code to make the final decision whether the label should be drawn or not. This option just gives it the opportunity to skip the label if that results in a cleaner UI.
