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).
