I'm perplexed by that too. We are migrating from Python to Rust simply because Rust is more suited towards unattended agentic loops, and we want to move in that direction. The results you get from a harness/agent/LLM with Rust are simply better than Python because the agent gets much better feedback from the compiler when it makes dumb mistakes. Python doesn't have anything even close to something like SQLx, which is a natural fit in Rust because of how Rust macros work.
