Keep in mind that yt-dlp doesn't just support YouTube, which-- notwithstanding the claims of "all DRM is malware" etc.-- probably won't download actively harmful code to your computer: it also supports a huge number of video streaming sites, including some fairly obscure and sketchy ones. Sandboxing in the interpreter that's at least as good as what you'd get in a browser is a must, because by design this is doing untrusted code execution.
