Servo has been using this since servo/servo#23196 to add a runtime check to some unsafe code, as discussed in PR rust-lang#59211. Stabilizing would help do more of the same in libraries that also have users on Stable.

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