I'd have to go back into my archives for the discussions about the PEP, but my
recollection is that we intentionally made PyImport_GetMagicTag() a public API
method. Thus no leading underscore. It's a bug that it's not documented, but
OTOH, it's unlikely there are, or would be, many consumers for it.
Strictly speaking, I do think you need to deprecate the APIs. I like Nick's
suggestion to make them C wrappers which just call back into Python.
