Note that author metadata recorded in the backport commit is the author of the backport commit, not the author of the original commit. Likewise the reviewers recorded in the commit message are the reviewers of the backport commit, not the reviewers of the original commit.

The current state of this script is known to be incomplete to some extent, but it can still be valuable.
