Feature Request: Permission to see country flag

I would love having a permission to allow/disallow receiving country flags for each client from the server.
For example, suppose I am moving countries regularly. I do not want other users to be able to track my location.

Currently, clients can turn off country flags, but there is no way as a server admin to stop clients from being able to turn them on. Specifically, there is no built-in way to prevent the server from sending out each user’s country to everyone else.

Why should the server admin be able to decide whether country flags are displayed or not?

As I said already, the disclosing of country information should be controllable for privacy reasons. Since it is the server doing it, I’d guess a server permission is the simplest way to implement it. But any way for a user to stop their country from being disclosed to other users would be fine with me.
