URGENT: review of deprecation notices before closing 21.08

The next release 21.11 will allow API/ABI breaking changes. The process is to announce such changes in the previous release notes. We are closing the release 21.08 this week so it becomes very urgent to review all these notices and vote (ack) or reject them now.

For convenience, I am adding those patches in a bundle for easy review:
