Dec 9th is just a suggestion; the idea being to have a date that covers
connectors that are being released right now, while enforcing some
migration window.
We will not reserve time for such a verification. Release testing is
meant to achieve that.
Since 1.16.x is unaffected by the removal from the master branch there
is no risk to existing deployments, while 1.17 is still quite a bit away.

Hello Chesney,
The overall plan sounds good! Just to double check, is Dec 9th the proposed
cutoff date for the release of those externalized connectors?
Also, will we reserve time for users to verify that the drop-in replacement
from Flink 1.16 to those externalized connectors can work as expected
before removing their code from the master branch?
Thanks,
Dong

Hello,
let me clarify the title first.
In the original proposal for the connector externalization we said that
an externalized connector has to exist in parallel with the version
shipped in the main Flink release for 1 cycle.
For example, 1.16.0 shipped with the elasticsearch connector, but at the
same time there's the externalized variant as a drop-in replacement, and
the 1.17.0 release will not include a ES connector.
The rational was to give users some window to update their projects.
We are now about to externalize a few more connectors (cassandra,
pulsar, jdbc), targeting 1.16 within the next week.
The 1.16.0 release has now been about a month ago; so it hasn't been a
lot of time since then.
I'm now wondering if we could/should treat these connectors as
externalized for 1.16, meaning that we would remove them from the master
branch now, not ship them in 1.17 and move all further development into
the connector repos.
The main benefit is that we won't have to bother with syncing changes
across repos all the time.
We would of course need some sort-of cutoff date for this (December
9th?), to ensure there's still some reasonably large gap left for users
to migrate.
Let me know what you think.
Regards,
Chesnay
