The symbol is marked as an internal symbol (starting with an underscore), so this should be a private symbol. However typed-ast is using that directly in the code. I would say the issue is more on the side of typed-ast. You already filed https://github.com/python/typed_ast/issues/169 and https://github.com/python/typed_ast/issues/170 talks about the end-of-live for that module.
