While I would agree with this line of thinking if the situation were as
you describe, it should be obvious that it isn't; nobody here uses or
has ever used a work email as committer address[1][2].  Nevertheless,
since this argument is about _your_ personal identity not mine, I'm not
going to stand against you on it.

Therefore I +1 Daniel's original proposal with thanks, and BTW I'm not
sorry for changing my name to use the hard-won ' accent on it :-)

I don't think these examples are normative.  There's plenty of evidence
that people look for ways to attribute contributions to individuals
rather than email-based identities.  See for example

https://gitlab.com/gitlab-org/gitlab/-/issues/14909
https://github.com/microsoft/vscode/blob/main/.mailmap
https://github.com/gradle/gradle/blob/master/.mailmap


[1] AFAIK gmx.net is a ISP-supplied address, not a work address.
[2] scrappy@hub.org and simon@2ndQuadrant.com might be
    considered work addresses, but they aren't really
