Right, "We'll just write the DMA subsystem in Rust" is not viable so long as there are platforms Linus wants for Linux that don't have a reasonable Rust story.

It would be very disappointing if that's what it takes, that somehow "Everything" is the lowest acceptable bar for "Anything" but I'd guess in the short term the only consequence is that the Rust priorities for 2025H1 get shorter by one item, no need to get Rust-for-Linux on stable Rust closer if in fact Rust-for-Linux is blocked until we can just rewrite everything in Rust anyway.
