I almost don't want to mention it since it's not very discoverable (and is never the first place I think to look), but git-rev-parse already contains a grab-bag of options unrelated to revision parsing. Many of the options relate to querying paths (--show-toplevel, --show-cdup, etc.) or other information related to a repository (--local-env-vars, --show-object-format, etc.). So, adding --show-default-branch may be one possibility.
