Comment (by flixos90):

 An alternative approach: Introduce an entirely new function
 `validate_option()` and do all validation including the filter in there.
 This function would then be called inside of `add_option()` and
 `update_option()` (''before'' `sanitize_option()`), and if an error is
 returned, make the function not change the value set and return false.
 This actually seems like a cleaner approach to me, but also like a bigger
 change. Let's discuss further.
