We should merge this, but the PR is out of date and our CI system is currently not working. We probably need to fix CI, update this PR, and then merge it.

@mfedderly You can notify me when the CI is fixed, then I'll update the PR.

@rycgar seems like the CI is working again, looking forward to merging this when you get around to it.
