> better code
I'm not disputing that Rust has its advantages; the issues I talk above are mostly problems with the community than the language per se. (On the other hand, we are yet to see how the "import antigravity" attitude will play out once the bits had enough time to rot - it does matter whether your ten-liner test program is only using libc because it was too much work to get a nice pretty-printing library, or whether you imported a pretty-printing library because you could, resulting in 2GB of transitive dependencies of which some have 10 users and 0 active maintainers. And then there's the supply chain security issues)

Surely depends on how fast-moving your field is - I have reused diagram code from late-'90s category theory papers, and recompiled more from source just to get the benefits of the pdflatex pipeline over the latex-dvips-ps2pdf one (selectable text, proper font rendering, hyperref). Repositories like arXiv also may need the ability to recompile old submissions automatically.
