It should read "Enable unstable features on unstable channel". That is you have to opt-in on unstable, and can"t use them at all on stable. So this is a documentation bug. |

I thought that is implicit? I.e. if you are on an unstable toolchain, you
already have unstable features? Or is the flag for opting out of unstable
festures on an unstable toolchain?
Even if it"s a documentation bug, it would be cool if the feature that I
expected would exist :D
It"s a pain having to install 2 rust versions in CI if you want to test
against stable but would like to use unstable format options and verify
formatting in CI using `--check`.

The documentation of
unstable_featuressays:But the option itself is only available on nightly. So how am I supposed to enable this if I am using
stablerustfmt?I wanted to use this to have unstable formatting options on a stable toolchain without having to install that one separately.
