This seems like an XY Problem <https://xyproblem.info/>. Why are you depending on a private implementation detail of the Go runtime? What happens to your code if that function is removed or its behavior changes? There is probably a better solution than creating that dependency. If nothing else by keeping it private rather than exporting the symbol.
