Potential idea for a microproject:

Add a new config setting:

    Defaults to true.
    If user.name and GIT_COMMITTER_NAME are unset or user.email and
    GIT_COMMITTER_EMAIL and EMAIL are unset, an implicit value is
    substituted for one or both of user.name and user.email.  If
    an automatically generated value is used for both name and email
a warning "Your name and email address were configured automatically..."
    is displayed.  If set to false, no or never, instead of a warning,
    an error is generated and the operation fails:

        *** Please tell me who you are.


          git config --global user.email "y...@example.com"
          git config --global user.name "Your Name"

        to set your account's default identity.
        Omit --global to set the identity only in this repository.

        fatal: implicit user identity not allowed

the advice portion can be suppressed by setting advice.implicitIdentity to false,
    but not the "fatal: implicit user identity not allowed" part.

Note that if "git config --system --bool user.allowImplicitIdentity false" is in effect, it should still be possible to clone (ref logs may be updated, but they should be allowed to use an implicit identity). In other words user.allowImplicitIdentity=false should only inhibit writing any new commit/tag objects that need the current user's name and email when it has not been explicitly provided.

I'm not sure how micro this is. :) I do think the amount of code involved is rather small though. Support for something like this has popped up on the list before. Perhaps "user.allowAutomaticIdentity" and "advice.automaticIdentity" would be better config names.
