Eloquent WithDefault not mapped on firstOrNew / FirstOrCreate / UpdateOrCreate

[phpsa]

• Laravel Version: 9.43.0
• PHP Version: 8.1.8
• Database Driver & Version: MySQL 8

Description:

Laravel has the options of withDefault on a relation eg:

public function settlement(): HasOne
    {
        return $this->hasOne(Contact::class)->where('type', ContactTypeEnum::Settlement)->withDefault([
            'type' => ContactTypeEnum::Settlement
        ]);
    }

Would be nice to have the defaults run through when calling for example in a magic helper we currently have:

 protected function processHasOneRelation(HasOne $relation, array $collection,  void
   {

       $relatedRecord = $relation->firstOrNew();

       if( $relatedRecord->exists() === false){
           $defaults = $relation->getResults();
           if($defaults){
               $relatedRecord->fill($defaults->toArray());
           }
       }
       $relatedRecord->fill($collection)->save();
   }

due to the getDefaultFor method being protected, it is not accessible in our helper.
