Yes... all I meant was actually that I would consider it consistent if both

<select>
   <option>foo
</select>

<datalist>
   <option value="foo">
</datalist>

work the same regarding the label. According to the current spec, the 
option in the select element has a label "foo", while the one in the 
datalist element has none. With the change I proposed, both would have 
the label "foo".
