I agree with yo 100%. Not being able to lazy load resources doesn't make sense. There are very few resources that are required with every page load. Even the DB or View objects may not be necessary much of the time with proper caching. I created my own resource manager that creates resources only when they are requested and this handles all of my resources. I still use a bootstrap class but it requests all resources from the resource manager.
