Even outside of competent maintenance or individuals being served by
ISPs, I think it is really that it is no longer the case that the
machines we get our mail on and the machines we do our work on are less
and less the same. Even as an individual, I can afford a Linux
workstation on my desk _and_ one to serve my mail. But I don't advertise
peff@xxxxxxxxxxxxxxxxxxxx as my email.
Which isn't to say there aren't people in the separate situation, like:

I think that is a good idea. Administrators of competent shared
environments can turn off the advice via /etc/gitconfig if they want,
and everyone else needs to opt into it consciously, which should help
reduce errors. I'm sure there will still be somebody, somewhere, who
complains about having to set the config, but that minority is hopefully
small enough to justify the errors saved by new git users.
Can you apply the patch below to my series as 4/3?

Subject: [PATCH] commit: allow suppression of implicit identity advice
We now nag the user with a giant warning when their identity
was pulled from the username, hostname, and gecos
information, in case it is not correct. Most users will
suppress this by simply setting up their information
correctly.
However, there may be some users who consciously want to use
that information, because having the value change from host
to host contains useful information. These users can now set
advice.implicitidentity to false to suppress the message.

Pretty straightforward. The biggest question is whether to suppress the
"Committer: XXX <YYY@ZZZ>" line, too. I kind of think it is useful if
you are intentionally using this feature; by definition if you are using
it intentionally then the information is of some interest to you.
