Yes; but what I'm talking about (Kbuild) is in-tree support for Rust. Bindings are regenerated when the kernel is built. As far as "how the Linux kernel likes to work" either it's in tree, or it doesn't matter. (Not my opinion per se, IDC, but look at upstream's collective treatment of ZFS and other out of tree drivers in general; they remove APIs they know external modules are using). I do generally find out of tree drivers to be a PITA to build outside of the kernel, and sometimes find curious things in their build scripts. Updating NVIDIA drivers seems to be...not great.
