Hm, it actually says it like this in the code :D

This is correct, but not ideal: https://rustc-dev-guide.rust-lang.org/stabilization_guide.html#updating-the-feature-gate-listing

cc @est31 maybe we want to special case this in the diagnostics

Yeah seems I've missed correcting that lint. For GATs, the stabilization version will be adjusted very soon, in the coming days, as we are close to the release cycle. But this needs to be fixed for future stabilizations as well. Working on a PR. @rustbot label bug

Yeah it warns correctly for lib features so only lang features are affected:
