Request for Soft Delete to not touch or change the updatedField

Currently I'm seeing that while deleting with soft delete, it also change the updatedField date.
So the actual updatedField date is replaced by Soft Delete.

/system/Model.php
line: 449-551

PHP Code:

            if ($this->useTimestamps && $this->updatedField) {
                $set[$this->updatedField] = $this->setDate();
            } 


And also, for insert data, it should be only fill createdField only, the updatedField should be NULL.
/system/BaseModel.php
line: 772-774

PHP Code:

        if ($this->useTimestamps && $this->updatedField && ! array_key_exists($this->updatedField, $data)) {
            $data[$this->updatedField] = $date;
        } 


Meanwhile, I commented those line, so that updatedField is in actual date.
I hope this can be implement in the next version.
Thanks

I finally use custome base model which can solve this case.

PHP Code:

protected function cbBeforeInsert(array $data) {
        unset($data['data'][$this->updatedField]); // to remove change date while insert
        $data['data']['created_by'] = user_id();
        return $data;
    }
    protected function cbBeforeUpdate(array $data) {
        $data['data']['updated_by'] = user_id();
        return $data;
    }

    protected function cbBeforeDelete(array $data) {
        $purge  = $data['purge'];
        //$id   = $data['id'];
        if(! $purge) {
            $this->useTimestamps = false;
        }
        return $data;
    }

    protected function cbAfterDelete(array $data) {
        $purge  = $data['purge'];
        $id     = $data['id'];
        $result = $data['result'];
        if(! $purge && $result) {
            $dataUpdate = [
                'deleted_by' => user_id(),
            ];
            $builder = $this->db->table($this->table);
            $update = $builder->update($dataUpdate, ['id' => $id]);
            $data['result'] = $update ? true : false;
        }
        $this->useTimestamps = true;
        return $data;
    } 


So, I'm not depend on /system/ files, to stay update
