That's your philosophy of pi and it seems you are taking it from deepseek. It's stated that pi wants to keep the agent loop minimal, not the code around the harness. Also those extensions in pi can sometimes be very bad, as it depends on the maintainer. And when it comes to cache handling of the best frontier coding model, it's much better that pi itself maintains it rather than some rando online.

No I did not ask AI for this. This is the understanding I have from working with PI for a year.

They also say so on their website ( https://pi.dev/ ): "Pi ships with powerful defaults but skips features like sub-agents and plan mode. Ask Pi to build what you want, or install a package that does it your way."

I fully agree on the quality of the packages. Can vary quite a bit. I stick to very popular ones.
