Yes, sure I know how it can be frustrating and I am sorry about that.
I forgot to review the RFC and I forgot to comment this deprecation notice.
Then it was pending like other deprecation notices, but no new deprecation
notice appeared for 18.02, and nobody did a comment on those patches.
So I think it is better to just postpone it for 18.05.
Anyway we can comment and work on the RFC in the meantime.
