This seems fairly non-controversial, given in particular that we do not say what exactly a "provenance" looks like. However, it does seem to me like we should involve @rust-lang/lang as well, given that this will make stable promises. Though I cannot entirely articulate what we are actually committing to -- I guess it is the fact that uninitialized memory is "real" as far as Rust is concerned, and distinct from all 256 regular initialized states of a byte. But that's long-established consensus, isn't it? |

We didn't feel like this was well-defined enough to go into right now, and didn't seem necessary to include right now.
