This is a bug for tracking the receipt of a committer agreement; it doesn't require account-level access or vouchers. This *might* be a duplicate; Erick says he sent the form in some months ago, so it's possible I have simply lost track of the back-and-forth discussion that covered his submission. If you wouldn't mind confirming its arrival, I'd appreciate that. I want to set him up with normal collaborator-level access on Rust. Thanks.
Never mind, found the dupe.
