We are trying to move extension to magento 2 and find out that here is 'view_block_abstract_to_html_before' in \Magento\Framework\View\Element\AbstractBlock in toHtml(), but here is no 'view_block_abstract_to_html_after' in end of toHtml() which dispatched when block is generated - which is quite useful if we need to control results of specific blocks. Is here any plans to add it release version of magento 2? It is extremely useful feature which exist in magento 1.x.x.
