This adds some clarification around how unstable features should be introduced, particularly when interacting with global config settings that may be read by older releases.
Note that the current set of unstable features violates some of these guidelines, and may deserve some attention in fixing up:
-Z profile-rustflags: it is an error ifrustflagsis found inconfig.toml. This could potentially make it awkward to stabilize if the user wants to place rustflags in their global config. I think that may be rare, though I can imagine some users wanting-Ctarget-cpu=nativeor similar.-Z codegen-backend: it is an error ifcodegen-backendis found inconfig.toml. I'm not sure about the likelihood of users setting this globally, but I could imagine people might want to opt-in to cranelift.codegen-backenddoes not requirecargo-featuresinCargo.toml, but it probably should since it is new syntax.-Z bindepsdoes not requirecargo-featuresinCargo.toml, but it probably should since it is new syntax. I understand requiring bothcargo-featuresand-Zis awkward, but each has independent reasons for being needed.
