The pleasantries description feels out of alignment with the practice outline as an example. The good message still starts with 'hello', it just doesn't treat it as a statement that requires individual acknowledgement. Which is great, that practice is great, but I think the framing could use some work.

But it also has a special badge so that can communicate to other people that you bundle polite greetings in with the payload of the message, which I think is weird, and is probably a clue that the author and I don't share a cultural context here.
