Answer 1

From CodeIgniter User Guide Version 2.1.4

CodeIgniter’s Hooks feature provides a means to tap into and modify the inner workings of the framework without hacking the core files. When CodeIgniter runs it follows a specific execution process, diagramed in the Application Flow page. There may be instances, however, where you’d like to cause some action to take place at a particular stage in the execution process. For example, you might want to run a script right before your controllers get loaded, or right after, or you might want to trigger one of your own scripts in some other location.

Not sure what you consider “reasonable” though, but the above summarizes it pretty well. They allow you to add additional behavior to core library classes at various points in the execution cycle.
