A quick search gave me:

    https://doc.rust-lang.org/nightly/unstable-book/language-features/strict-provenance-lints.html

The linked tracking issue is closed which seems like a mistake, since
it's not yet stabilized. I found a different issue tracking it though:

    https://github.com/rust-lang/rust/issues/130351

We probably should use both in that case:

    #![feature(strict_provenance_lints)]
    #![warn(fuzzy_provenance_casts, lossy_provenance_casts)]

I don't want to push more work onto this series, so it's fine to leave
them in. Thus:

We can either make this a good-first-issue, or if you also want to
tackle this, then go ahead :)
