I agree with you on that. Such stuff usually stem from just someone (doesn't have to be Justin or Alonso) mentioning an idea, and because it was brought up in discord, it stays there and people develop on it there. Like I mentioned previously, I don't see how we are going to stop people from doing that on a platform that is made for discussion. Everyone just have to accept that there are two official platforms for discussion, and that not everything will be discussed here.
That said, maybe the term [official] in the topic and having a staff representative (iirc) voicing out in favour of something might have caused some panic because instead of "I want some views on this suggestion made by a user", people actually see it as "we're thinking of implementing this, what do you think?"
