Thanks for creating the channel! As for the question of what has to go in #raku-debate, and what can still be discussed in #raku even if contentious: Ultimately it'll probably have to be decided through a consensus by the community or steering council. My thinking behind

The purpose would not, of course, be to say: “Anything contentious must go in #raku-debate and has no place in #raku”.

is: It makes sense to require that the bulk of any contentious discussion happen in #raku-debate, but in my opinion what should still be allowed in #raku (as long as one doesn't abuse this) includes:

• to begin any discussion in #raku (moving to #raku-debate when asked to),
• to mention the state of a #raku-debate discussion in the main channel from time to time,
• to ask people from #raku to look at an ongoing or logged discussion and/or to add their opinion.
