I would recomand to add customization.
The one who do not need it just skip it and go on reading while the one who insist on CC might not even read the story if there is no customization.
But on the other hand there are really famous stories without CC so CC is not the major factor which makes reader to stay with the story - at the end it is always good writing and good story which does keep them reading.
so if you feel like you do not want to have CC I would not worry that much about it.
