I am not sure that the analogy works at all. Any child can download a "Feed the Beast Launcher" or somesuch that's able to install a modpack with a single click. For some packs, that amounts to hundreds of mods. Who cares if that requires hacking bytecode, that's all abstracted away. It's even abstracted away from developers, ever since Forge was released.
