I agree with you completely. If rust is so great why not make a new kernel with it and compete? or fork and start rewriting subsystems?
I do also understand the frustration when an open source project strings you along (me: can I join your club?), ask for this and that (them: sure if you pay your dues), ensuring your cover every "important" person's pet use case (them: and also buy us lunch), then publicly snark about the whole thing (them: this new guy know about no mustard on the lunch!) and kill your failing motivation (me: oh, sorry).
That's why the fork is so appealing. If it's good enough for long enough you get to join the club.
What I don't get is the complaints from the Rust people.
If Rust truly is zero overhead on the C side of things then they should be just able to fork Linux indefinitely without any worry about what upstream does. Just fast forward every change and you're golden.
Then they can write every driver they can imagine to their hearts' content.
The fact they aren't doing this tells me that the promise that this won't impact C people at all isn't much of one.
The problem is that they might want their drivers to actually work on people's existing Linux systems without having to force them to use a forked kernel.
It's like telling people who want JPEGXL in Firefox to "just" fork the browser, ignoring the massive extra effort that you actually have to convince everybody to use your fork instead of the original.
What extra effort? If you match upstream it's a drop in replacement and anyone who cares will use it. If they don't it's because they don't care.

Linux is the most important open source project ever. The barrier to entry is, actually, shockingly low.
