The propouse of this module is to intercept the normal workflow of page rendering of Magento 2 and force the exit the rendering of the page if a block that is uncacheable is reached. If the block is uncacheable, the wholepage get it's cache disabled and cannot be handled by file cache or Varnish cache.
This is usefull to debug any module that might contain the following entry inside one of it's layout definitions (catalog_product_view.xml for example):
....
<block name="thridpartblock" template="Vendor_Modulename::confirm.phtml" cacheable="false">
....This module is good to help troubleshoot when your any page of the system is not having it's cache generated by Magento (in Varnish or in Disk Cache) and you don't know which is the block that is making this behaviour to happen.
