I'm still a little disappointed it doesn't ignore /etc/shadow by default. I can't imagine a valid use case for keeping /etc/shadow in source control.

Clearly there are reasons to keep /etc/passwd in version control. Changes to /etc/passwd often need to be synchronized with changes to /etc/shadow.

For something like professionally administered servers accessible only via ssh asymmetric keys, /etc/shadow may not be considered so sensitive that it's worth the risk of having it be an exceptional cases in version control.
