An excellent point. Though the more I work with Kohana, I find it ends up being an unexpected side-benefit: I'm forced to go through the actual code of the subsystem in question when I want to learn something tricky about how it works, which means that I thoroughly understand it, as opposed to just dox-level familiarity. They are working on better dox, though.
