You're right; I carried over the tag from the previous iteration
thinking it addressed usage when it actually suggested the lints. The
lints can't be enabled yet because they are not stable (not just in
our MSRV).

Correct. There are both behavior-preserving exposed-provenance
spellings and cases that deliberately avoid exposing provenance. I
will split those as you suggest.

Thanks for reviewing!
