Comment 23 for bug 1957932

Now that the new rustc has migrated from -proposed, I'd like to move forward with the rustc MIR, as I believe all the issues raised during its review (#3) have been addressed one way or the other, see #7 and subsequent updates since.

We also have a provisional ACK from the security team (I'll keep working on surfacing the vendored deps data in a better way than Cargo.lock!).

The seed changes are in a MP at https://code.launchpad.net/~schopin/ubuntu-seeds/+git/ubuntu-seeds/+merge/416688

@paelzer could you confirm that we can move ahead, and perhaps review the seed change?
