Yes, rust-next works, but I was imagining renaming the current rust to something like default-rust-build, then defining a new ‘rust’ which will be continuously updated to the latest version of rust.

I think a user centric design would name the latest rust as just ‘rust’, while letting the package-manager implementation detail have the longer name.
