There are some old, undocumented functions that exist in public namespaces that were maybe useful some time ago. Since these are not hidden in private namespaces, should these function undergo the normal depreciation processes?

So looks like _slow_pivot is used in one panel test, so that should be kept for now.

pivot_simple is available as pd.pivot, probably needs a new issue to discuss.
