What happens to hidden-xs option from 1.4.1?

[instruccionesaldorso]

What should we do with old grids coming from 1.4.1 version that had in one of "xsCol" columns the value "hidden-xs"?
The option to hide these columns has been removed for 2.0.1 version.
Shouldn't an option "d-none" exist?

I solved this that way (adding "d-none" to "xsCol" and "d-*-block" to all other cols but "xsCol"):

            case 'xsCol':
                $optionList = array(
                    array('LLL:EXT:bootstrap_grids/Resources/Private/Language/locallang_db.xlf:grid.label.autoLayout', 'col'),
                    array('25%', 'col-3'),
                    array('33%', 'col-4'),
                    array('50%', 'col-6'),
                    array('66%', 'col-8'),
                    array('75%', 'col-9'),
                    array('LLL:EXT:bootstrap_grids/Resources/Private/Language/locallang_db.xlf:grid.label.moreWidth', '--div--'),
                    array('8.3%', 'col-1'),
                    array('16.7%', 'col-2'),
                    array('41.7%', 'col-5'),
                    array('58.3%', 'col-7'),
                    array('83.3%', 'col-10'),
                    array('91.7%', 'col-11'),
                    array('100%', 'col-12'),
                    array('LLL:EXT:bootstrap_grids/Resources/Private/Language/locallang_db.xlf:grid.label.moreOptions', '--div--'),
                    array('LLL:EXT:bootstrap_grids/Resources/Private/Language/locallang_db.xlf:grid.label.notset', ' '),
                    array('LLL:EXT:bootstrap_grids/Resources/Private/Language/locallang_db.xlf:grid.label.variableWidth', 'col-auto'),
                    array('LLL:EXT:bootstrap_grids/Resources/Private/Language/locallang_db.xlf:grid.label.hidden', 'd-none'));
                break;
            case 'smCol':
                $optionList = array(array('LLL:EXT:bootstrap_grids/Resources/Private/Language/locallang_db.xlf:grid.label.notset', ' '),
                    array('25%', 'd-sm-block col-sm-3'),
                    array('33%', 'd-sm-block col-sm-4'),
                    array('50%', 'd-sm-block col-sm-6'),
                    array('66%', 'd-sm-block col-sm-8'),
                    array('75%', 'd-sm-block col-sm-9'),
                    array('LLL:EXT:bootstrap_grids/Resources/Private/Language/locallang_db.xlf:grid.label.moreWidth', '--div--'),
                    array('8.3%', 'd-sm-block col-sm-1'),
                    array('16.7%', 'd-sm-block col-sm-2'),
                    array('41.7%', 'd-sm-block col-sm-5'),
                    array('58.3%', 'd-sm-block col-sm-7'),
                    array('83.3%', 'd-sm-block col-sm-10'),
                    array('91.7%', 'd-sm-block col-sm-11'),
                    array('100%', 'd-sm-block col-sm-12'),
                    array('LLL:EXT:bootstrap_grids/Resources/Private/Language/locallang_db.xlf:grid.label.moreOptions', '--div--'),
