In rust-lang#12115, we explored how we can let stable projects experiment with `[lints]` to provide feedback. What we settled on is switching from the `cargo-features` manifest key to the `-Z` flag as `cargo-features` always requires nightly while `-Z` only requires it when being passed in. This means a project can have a `[lints]` table and have CI / contributors run `cargo nightly check -Zlints` when they care about warnings.

I wasn't quite sure what language to use and most likely a user would have something doing error reporting, like CI, so it should be fine.
