Should Snowflake proxies have a way to identify themselves to the broker

Would it make sense for us to have an identity key (or something similar) for Snowflake proxies to allow them to identify themselves to the broker service.

This would allow us to later build reputation systems for the proxies and distribute snowflake proxies in a smart way based of stability/uptime. The downside from a privacy perspective is that the broker can follow the Snowflake proxies' movements on the internet, which means we might want to make it optional.
