I think that we'll plausibly end up with a stronger guarantee than what's discussed here, but the basic one of "if it's 'executed' it'll definitely be evaluated" as proposed here seems like an entirely reasonable and hopefully uncontroversial minimal first step. @rfcbot fcp merge |

Team member @joshtriplett 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! cc @rust-lang/lang-advisors: FCP proposed for lang, please feel free to register concerns. |

Fixes rust-lang/rust#112090
I think this has been our intention for a while (ever since rust-lang/rust#67191 landed), but was never properly decided, so it likely needs t-lang FCP.
