Alternatively, you can drive "git show -s" with "--format" and you probably can produce a machine parseable output. But it does not change the argument fundamentally. The point is that "for-each-ref --format=%(*field)" that peels only the first layer would not have helped all that much, if somebody really cares about each levels of nested tags. They would have been relying on a solution to deal with the second and further layers anyway, and that solution would have been working with the first layer, too.
