I covered that in the first email, highlighting the importance of
using an easily remembered, already reasonably unique piece of
information (like a name/email pair) that you don't need to change.

The problem is that the name/email pair (as in the 'name' and 'email'
config variables) is NOT ONLY subject to typos, but it is ALSO subject
to changing email accounts and changing real life names.
If you don't use the uuid `field' that I propose, then everything
would be just like it was before. If you do use it, then you can
easily identify all of your own contributions regardless of what your
name/email du jour is.

The user doesn't have a damn choice!
The email can't be kept consistent over time because the tools expect
it to be and/or use the actual physical email used to send/receive
stuff. It's information that CONFLATES identity with whatever
tool/system you're using.
For instance, Michael Haggerty cannot reasonably use
[user]
name = Michael Haggerty
email = mhagger@xxxxxxx
because he likely no longer has that email account to use. He is
forced to change it and therefore forced to make his identity
confused.
I'm proposing ALLOWING him to say:
[user]
uuid = Michael Haggerty <mhagger@xxxxxxx>
name = Michael Haggerty
email = mhagger@xxxxxxxxxxxx
Heck, let's say he works at Red Hat as well; he might make some
commits under this config AT WORK:
[user]
uuid = Michael Haggerty <mhagger@xxxxxxx>
name = Michael Haggerty
email = mhagger@xxxxxxxxxx
Then, he can make, say, commits to the Linux kernel repo for both work
and hobby related issues and still be recognized as the same person.
That is, he can have some commits under "Michael Haggerty
<mhagger@xxxxxxxxxxxx>" and other commits under "Michael Haggerty
<mhagger@xxxxxxxxxx" and still link them all together as the same
identity with just the uuid "Michael Haggerty <mhagger@xxxxxxx>".
Sincerely,
Michael Witten
