Is there something notable about this?

Looks like it's advertising Twitter's new feature to control who can respond to public tweets.

Specifically, it's a demo of "only allow replies from mentioned users".

The lack of random Twitter users trying to inject themselves into the conversation is kind of refreshing, TBH.

If the conversation is supposed to be private, have it in private. This is like a walled garden with a glass wall.
