Without having looked into it, I find it plausible that it could take several patchsets to come to an assessment of consequences and conclusion. Especially as they happen alongside assessments and discussion. The patchset number may also be largely irrelevant depending on what was changed.

This is the first time I have seen a Wikipedia weblink that sets a display theme via parameter.

Is this a subtle campaign for everyone to use vector? /s :P

I think the issue with that would be increasingly working catch-up on newer developments of replaced functionalities.

If your end-goal is integration then it’s better to integrate early rather than late.

Developing and maintaining an interface and abstraction and having to keep that up to date is one thing. But after replacing some modules and components, any developments on their originals raises the question of how does that apply to our Rust module? If it already were in the Kernel and had replaced that module or component, that effort would not arise.

You say it’s “needless” complexity. But that’s what’s up for debate, and most people, including Linus seem to disagree with you.

It’s not a matter of whether Rust is demonstrably superior and more secure, that it is seems to be the common understanding and agreement.

A new project matching reasonable Kernel feature-parity would be too much effort. It’s unrealistic.

The value is in moving the Kernel itself into a safer space and tool-space.

The idea that a technically superior solution would naturally supplant an earlier one with a huge market penetration and stability is wishful thinking. We see it in many areas. Without significant issues people at large will stay with what they know and what is popular.

Title: “is finally rolling out to the wild”

Ahead of Legion Go S shipping, we will be shipping a beta of SteamOS which should improve the experience on other handhelds, and users can download and test this themselves.

So, neither that product is rolling out yet, nor the SteamOS beta is rolling out yet?
