One of the first things I do when starting work on a new codebase is to step through every single line of code (especially the framework bits). I'm usually the first one to discover silent misconfigurations that have been there for years. That being said, once I fully understand the entire stack and how we're using it. I can abuse the hell out of it and make it do anything I want it to do; even beyond anything the original authors ever considered. Most people only take the time to get surface-level knowledge of the entire stack, and either re-implement something they can get for free, or don't take full advantage of what the stack gives them. That being said, getting that knowledge without a debugger is nearly impossible.
