Comment (by nikolov.tmw):

 > I personally think checkboxes do not need to have custom values and they
 should only be true or false, since they are usually used for switching
 something, like switch to whether displaying tagline or not.

 Except for, there are situations where checkboxes need to save their
 custom values. For example, you can use checkboxes to select what filters
 will available in a search form - "categories", "tags", "months"(yes, not
 the best example, but should get the point across). Checkboxes are not
 only on or off.
