Personally, I believe it’s definitely a reasonable suggestion, and makes a lot of sense - especially considering it is a new feature, so players will want to play around with it (even the ones who do follow the rules), and I can completely understand why some players may want to toggle random announcements in chat. I would urge you to take your suggestion to our dedicated player suggestions website - Feature Upvote, where it’s more likely to be reviewed - and it’ll give other players the chance to upvote and share their feedback.
