I'm on the lookout for something similar, so that we can be sure who
introduced some change into the central repo.

One of the spots that we're looking for in this, is a model something
like what follows. Firstly, a "proxy maintainer" (PM) is a developer
with commit rights to the central repo, that's willing to proxy commits
by an outside source for some specific package. Think of them as the
kernel subsystem maintainer, but many more of them. The PM is still
expected to verify the work before passing it on the central repo.

So we have a commit with author+committer being the outside source, and
now we want to record (in an easily reviewable fashion) that a specific
changeset was introduced to the central tree by the PM.

Not sure of the best route to trace this data. Signing the SHA1 makes
the most sense, but need to be able to do that without polluting the tag
namespace.

If the changeset does not have an associated signature, we'd like to
reject it at the central repo.
