The existing (( $+functions[_git-foo] )) || test also solves it. The
only thing you need do is put your overrides in $fpath.

In practice, I doubt many people ever do. And if they do, we've probably
done a poor job somewhere.

This function existence check is not a pattern I followed elsewhere.
There are a few things that were done somewhat differently in _git
compared to other functions and some of that has been copied. I don't
see the point in the double initial underscore naming on some functions.
This particular test was rather annoying before $functions_source
existed because it made it more difficult to fully reload all _git
functions.
