Lack of interest Easier way to add own Order By Clause

[xf_phantom]

Wouldn't it make sense to allow coders to set the orderbyClause without overwriting the model?
Just take a look at http://xenforo.com/community/threads/getusers-order.66579/
It's not possible without creating a own model and overwriting prepareUserOrderOptions

Is there any special reason, why the order must be available in the choises array?

public function getOrderByClause(array $choices, array $fetchOptions, $defaultOrderSql = '')
	{
		$orderSql = null;

		if (!empty($fetchOptions['order']) && isset($choices[$fetchOptions['order']]))
		{

			$orderSql = $choices[$fetchOptions['order']];

			if (empty($fetchOptions['direction']))
			{
				$fetchOptions['direction'] = 'asc';
			}

			$dir = (strtolower($fetchOptions['direction']) == 'desc' ? 'DESC' : 'ASC');
			$orderSqlOld = $orderSql;
			$orderSql = sprintf($orderSql, $dir);
			if ($orderSql === $orderSqlOld)
			{
				$orderSql .= ' ' . $dir;
			}
		}

		if (!$orderSql)
		{
			$orderSql = $defaultOrderSql;
		}
		return ($orderSql ? 'ORDER BY ' . $orderSql : '');
	}

Couldn't you introduce probably a new feature where we could set e.g. $fetchOptions['alternative_order'] which would be used if

		if (!empty($fetchOptions['order']) && isset($choices[$fetchOptions['order']]))
		{

isn't true?
