It wasn't going to work without ample support within the kernel.

At a minimum, all prominent developers would have to be convinced and ready to put a lot of effort into this.

As this was never the case, Linus should have put his foot down with a clear No, thus preventing the conflict and overall waste of resources we're seeing.

Rust devs would still be able to fork or otherwise (much better idea imho) work on their own kernel, hopefully with a much better design.

Redox is doing this, with a microkernel multiserver approach.
