Non trivial software projects of course require a bit more organization than most kids will devote to their legos. The ideal solution is to keep your software small and simple so you barely need to think about organization, but if you can't keep it small and simple, then you better not let it turn into a 15kg bag.

Pi is much smaller and simpler than cc, and it's a finished product, not necessarily DIY "legos". You don't have to build plugins for it, and many people say it's superior to CC / codex / OpenCode out of the box. If you do want to build plugins, it already provides you with a well organized system to build around.
