Or poisoining the macro? Or something else? > Should it be removed? In which release? Sorry if I was not clear. Not necessarly remove the macro for this release. But I think we should announce it and remove it, following the process. I suggest: - for 18.05: send the deprecation notice + add a comment in the .h saying that the macro will be deprecated in 18.08 (or 18.11, there is no hurry if there is the comment) - for 18.08 (or 18.11): remove the macro (I don't think poisoining is useful in this case).
