In these cases, there is no identifying information in the commit itself, but externally in the organization's HR and IT departments where identifying information is tightly controlled.

I wish git would make this a core feature.  I think it is one of the
few oversights in the core design of git that there isn't a built
indirection on author and committer data.  It should be possible to
"forget" an author or committer without having to rewrite the repo.
IMO, one day in the future this design deficiency will cause some very
expensive remedial work in the git space, and IMO it is only a
question of when, but sods law says it will be at some very
inconvenient time.

It really should be technically simple to remedy as well, replacing
author and committer data with a hash or ID which is used to indirect
into a file of author information that is *not* version controlled
would essentially solve it.  If someone wanted to change their name
they would update the file, if they wanted to be forgotten they could
simply delete that line from the file and push it.  While not a 100%
complete solution it would go a LONG way to address most people's
privacy concerns and other practical identity management concerns (eg,
"my email changed"). The .mailmap support is just a bandaid, it
doesn't actually address the core problem and in fact in some ways it
makes it worse. If git provided support for hooking the id lookups
then queries to resolve the ID or names could be made to a third party
software or service, like an open source service for the public, or an
internal service owned by HR in the corporate context. It isn't rocket
science, it just requires recognition that names are not static
identifiers.
