Its a good question.

This bit me when we tried to use it via a beta build: https://www.omgubuntu.co.uk/2025/05/ubuntu-25-10-rust-sudo-rs-change

Ubuntu is removing core utils and replacing them with supposedly plug and play replacements that work exactly the same. In practice its already breaking some builds ( https://www.phoronix.com/news/Ubuntu-25.10-Coreutils-Makeself ), which is unfortunate. I dont care if core utils are rust or not to be honest. But I DO want things to be rock solid stable in our environment.

There are MANY articles on techrights.org on rust and Microsoft as well, but I don't know enough about the subject to verify any of the claims other than Microsoft seems to have a interest in getting people to use rust more. They are one of their biggest backers. And it would be unfortunate if yet another open source project becomes...influenced by MS and their needs.
