Setting aside whether or not I agree with the premise that smaller dependencies are worse for building system binaries (I think Nix provides a compelling counterargument), how is vendoring Rust dependencies "like C" (the same way Firefox and the kernel do) a regression from building C? All Linux dependencies are already vendored, and even without access to crates.io, getting access to Rust's language features is still a Pareto improvement over C, not a regression.
