The reflection and hot patching features are often called out as negatives, and in general I agree, but for the most part, they're non-factors. All of the "find_x_by_id_and_status()" methods that rely heavily on reflection are all available with a more general, maintainable "find_by()" method which just takes a hash of parameters. And in practice, I'm not sure how much custom hot patching is actually used in production codebases. Overall it's mostly a red herring which detractors have vastly overstated.
