Due to a priority shift this request has slipped to the backlog. I hate to bring bad news. I will continue to provide the feature team your feedback and votes.
Hopefully this will move back up in the queue soon.
Thank you for the feedback. Changing the default setting is under review by the feature team, and your feedback is very useful as they are evaluating.
The option to “discard” suggested contacts in your chat list is rolling out to users. We will be making further changes to make suggested contacts more relevant for new users in the future as well, so marking as partially completed. Thanks for your patience with this one.
