 Replying to [comment:2 westonruter]:
 > There is a problem with your alternate solution to move the
 `apply_filters` call: this needs to be done inside the `validate` method
 because if filters are used for validation, then if a plugin calls the
 `validate()` method somewhere else then it won't then work. It is intended
 that the `validate()` should be able to be called from other places than
 just `validate_setting_values()`.

 Oh yes, I got your point.

 > I don't really see applying filters a second time to be a big problem.

 Then Option-1 solution is better instead of introducing new filter. And
 also developer no need to rely on two different filters.
