Thanks for spotting it! Seems like an omission from the PR title. Unfortunately rather common :frowning:

Remove let_underscore_must_use from list of uplifted lints by Mark-Simulacrum · Pull Request #103825 · rust-lang/rust · GitHub fixes this on master, though we likely won't backport it to stable as that currently requires a full rebuild which doesn't seem worth it.
