For cg_clif I'm getting Failed spawning proc-macro server for workspace /home/gh-bjorn3/cg_clif: no sysroot because of https://github.com/rust-lang/rustc_codegen_cranelift/blob/0103c583fa01dd21d49fa9d5b2009e4c217659e2/.vscode/settings.json#L18-L45 This warning is completely useless as there are no proc-macros in that workspace at all and if anything risks obscuring genuine warnings.
