No it doesn't solve the impedance mismatch, but the YAML project would
be more flexible than the git config file.

You're right, I had forgotten this feature completely :x

Perhaps that was the better way to go...

How would (the presumably few) existing users of this feature be

Currently with the config file, there are problems with interop between
git-svn users that do git <-> git repo sharing, an updated version with
the "placeholder added" .gitignore would allow git <-> git repo sharing,
but only between users of newer git versions.  Perhaps that's fine and
better than the current situation.
