Hidden telemetry was my big concern, yes; the abort thing wasn't caught as a security thing by DeepSeek V4 Flash but it was mentioned by Claude 4.7 Opus (I wanted to compare and contrast here), and Flash brought it up later when I asked it about performance tuning.
`cargo add` tip is very helpful, I had a hunch this happened in my own Rust project and I think you just filled in the missing piece for me there.
To me panic=abort is much safer security as it means you’re unlikely to enter weird states due to incorrectly handled unwinding. The only attack vector is a DOS attack which is a short term thing that’s easily rectified.
