oh it evens says so in the output... 🤦‍♀️

Oh, yes. Thank you for bringing this to my attention! I need to do a new release after moving from tracking 1.72 to tracking a specific nightly. The code in the repo should always be buildable. I'm currently at RustConf and reworking the reachability logic to support multiple lints (beyond panic access) in a more reasonable way and was waiting to have that done before doing a new release. I'll update this ticket once things are more stable.
