duplicate of #70041

Thanks. @jonas-schievink Tangential, but do you happen to know if there's an issue tracking the missing components in latest nightlies? i.e. when I do rustup update nightly it has to go back to the 2020-03-18 version before it finds one which has all the necessary components (more recent ones are missing things like rustfmt-preview and clippy-preview).

[jonas-schievink]

issues for that get opened automatically, eg. #70280

Thanks!
