Its just nightly for now, but when Cargo v1.80 releases we would need a permanent solution anyway. Couldn't we just always emit those instead of gating it behind an unstable feature or does this break anything?

Hmm, it produces a warning when using v1.70:

warning: cargo:rustc-check-cfg requires -Zcheck-cfg=output flag

I thought it would do more, but seems like the fix is actually just that simple.

It actually found a bug, this is great!
