There's one fun problem here technologically for proxy-maint, but
getting the conditions right for it to occur happen very rarely.

1. Assume the proxied maintainer has a git repo, where they commit

2. Assume their proxy has said git repo as an alternative remote, for
which they relay work. ( That is, they work closely together directly
instead of via github pull requests and textual patches )

3. ::gentoo is quiet, and the proxied maintainer has rebased their own
work on top of ::gentoo, setting Committer: metadata and signing

Then, in that situation, it is trivial for the proxy to relay those
commits verbatim to ::gentoo, without changing either Committer: or
signature data.

Standard git tools will not attempt to even *change* these commits even
with an explicit rebase, because Git will detect that nothing needs to
change, and will no-op the rebase, leaving Committer and Signatures
intact, degrading to a fast-forward merge.

It seems like it would happen not-very-often, but ... 

git log --show-signature --format=fuller --committer=".*@\([^g]\|g[^e]\)"

Well, the last example happened in 2017, so maybe something happened
*since* then that prevented this situation occurring via other means?

To the best of my knowledge, Michael isn't a Gentoo Dev.
