> No network access. No filesystem. Nothing.

Ironically, any c++ app I've written on windows does exactly this. "Are you sure you want to allow this program to access networking?" At least the first time I run it.

I also rarely write/run code for windows.

Yeah, but if that app was built using a malicious dependency that only relied on the same permissions the app already uses, you’d just click “Yes” and move on and be pwned.
