That's not a decision that can or should come out of a patch review. I agree it's a possible decision, not something unthinkable. But if it were, it should be taken at a completely different level.

Basically, it's an obstructionist, uncivilized thing to hold up every discussion about a topic that you get to participate in by insisting the topic shouldn't be discussed in this forum. It's perfectly OK to advocate for the removal of Rust from the kernel, it's not ok to bring this up in every random Rust patch while the consensus is that Rust has a place in the kernel.

The kernel doesn't really have a better system mechanism for having these sorts of decisions made unfortunately.

I would quite like my laptop to keep working, and half its drivers are rust…

The Linux drivers can be maintained in a downstream fork. Ultimately that seems to be what upstream wants, unfortunate as that may be.

Then you (and others interested in running Linux on fruit company hardware) can sponsor someone to rewrite those drivers in a way that fits the Linux project.
