Comment (by stephenharris):

 Currently the third option for `register_setting()` is a callback, and for
 reasons for backwards compatibility that callback cannot be hooked onto
 `sanitize_option_{$option_name}` with the three arguments that are
 available (see #15335) - however, if we now support an `$args` array with
 `sanitize_callback` key then there are no backward-compatibility concerns,
 so  we could pass all three arguments to ''that'' callback.

 Admittedly it involves another if statement, and another degree of
 complexity - but what do people think about passing all three arguments
 when the callback is specified in the `$args` array?
