Yes, this was intended for the wg-chairs list, and I can blame it on technology that tells me what to do.
(new machine learning capabilities in my email client, I have been told.)

Now, it has served its purpose in 
announcing what the wg chairs will be talking about.
Which by the way is public since RIPE 67:
https://www.ripe.net/participate/ripe/wg/cc/agenda

and you can find the summaries at 
https://www.ripe.net/participate/ripe/wg/cc/summaries

So while the lunch is behind closed doors, there is transparency.

To answer the follow-up question at the same time: 
The plan is to publish a revised proposal based on input from the discussions, and have time for discussion 
on the Friday morning session.
