Comment(by nacin):

 I imagine this was done to allow a callback to then modify more than just
 the variable returned, but also these additional variables passed by
 reference. (Any changes done to them would then be reflected in the
 calling code.)

 For this, you'll want to consider do_action_ref_array,
 apply_filters_ref_array, or potentially a simple compact() then extract()
 to ensure that plugins can still change what they used to be able to
 change.
