Usually. But then again Linux was a rewrite too. Sometimes unnecessary things become critical, and the distinction is only clear in hindsight.

From what I recall, Linux was also Linus doing something because he wanted to, not necessarily because there was a business driver. I'm not saying don't, its just good to understand the motivation.

The concept of OSes use file cabinets of papers as part of the abstraction layer. Breaking from that mold might prove fruitful.

People rewrite things in Rust, not because of business reasons, but because they want to. What’s different here?

isn't it possible for there to be overlap between "because they want to" and "because it's necessary"?
