To be honest, I won't even consider it until Linus officially accepts Rust as a second language in the kernel, instead of as an experiment. The vb2 framework can certainly use some more work, and esp. better support for codecs, since that's where the main pain is at the moment. But I would need to see a proper proposal first.
