thanks a lot for your questions. I think each of them deserves its own thread. Thus, I created three new threads in the proposals forum.
To answer just the question whether there will be a separate forum/mailing-list for such kind of discussions. Probably yes. But I assume we will get one after a successful creation review. Until then simply put everything into this forum. I used a topic prefix "[CR]" to distinguish code recommender topics from other topics in this forum.
Thanks again and please find my answers to your questions in the newly created topics. I'm looking forward to your replies.
