Team member @joshtriplett has proposed to merge this. The next step is review by the rest of the tagged team members:

• @calebcartwright

No concerns currently listed.

Once a majority of reviewers approve (and at most 2 approvals are outstanding), this will enter its final comment period. If you spot a major issue that hasn't been raised at any point in this process, please speak up!

See this document for info about what commands tagged team members can give me.

[calebcartwright]

There was a suggestion on a rustfmt issue that we apply some sort of indicator that the set of Cargo.toml prescriptions is not exactly active/enforced, and I think that has some merit to it.

I don't think it's absolutely necessary, but perhaps a small disclaimer note at the top or bottom would be beneficial

The final comment period, with a disposition to merge, as per the review above, is now complete.

As the automated representative of the governance process, I would like to thank the author for their work and everyone else who contributed.

This will be merged soon.

@joshtriplett: I'd also like a small disclaimer like Caleb asked for (#120072 (comment)).
