This needs team confirmation since the linked comment only mentions a revert. @rust-lang/libs-api could you take a look?

@rustbot label +I-libs-api-nominated

Time check, we have about three weeks until the branch. If there is no consensus before then, we can just revert c89b6a9.

This seems useful for catching bugs, since it'd almost certainly be a bug to ever call this.

cc @Amanieu just in case, since this PR does seem different from your #146410 (comment)

But you checked your box here, so I'll leave it as waiting-on-bors on the assumption that you've changed your thinking since then.
