Nobody is proposing replacing code right now. Maybe that will happen eventually, but it's off limits for now.

R4L is about new drivers. Not even kernel subsystems, just drivers, and only new ones. IIRC there is a rule against having duplicate drivers for the same hardware. I suppose it's possible to rewrite a driver in-place, but I doubt anyone plans to do that.

There is a binder driver rewrite in rust. Companies who care are certainly rewriting drivers. If there is pushback in upstreaming them that will cause a lot of noise.
