Incosistency: the event «controller_front_send_response_after» is removed from Magento 2, but the event «controller_front_send_response_before» is left

The controller_front_send_response_after event was in Magento 1.x:
https://github.com/OpenMage/magento-mirror/blob/1.9.2.2/app/code/core/Mage/Core/Controller/Varien/Front.php#L182-L186

But it is absent in Magento 2.
Magento 2 has the controller_front_send_response_before event:
https://github.com/magento/magento2/blob/2.0.0/lib/internal/Magento/Framework/App/Http.php#L125-L127

But Magento 2 has no controller_front_send_response_after event:
https://github.com/magento/magento2/blob/2.0.0/lib/internal/Magento/Framework/App/Bootstrap.php#L252-L261
