Do you know what percentage of users right now are connected to the top three relays?

My assumption is that it’s more than 90%. 

If I’m right (>90%) then this gravity will be hard to fight. The large relays will become stronger through network effects. 

I remember reading that the devs were going to try an inbox / outbox solution where the large relays would be used for addressing. Is that still the plan? I didn’t see any discussion on removing the dependency on the large relays. 

Did I miss that? Is there a way to remove the client dependency on the large relays?
