I always find that super creepy. I mean i know my devices leak my position from country level all the way up to centimeter accuracy. I mean i know you can do that but somehow i don't want it to be rubbed in my face like that.

Besides that would mean that you would need to keep some kind of status of where a person resides. There is no metadata in my messages that should reveal my location, so how can new users know they are my neighbours?
