All that is cool, but I don't want Signal to advertise my presence to anybody that has my phone number when I first log in after a fresh install. I have only a handful of people that know and we negotiated that face to face prior, Signal breaks that trust
That would be a really nice option now that you mention it. Like a "fresh start" where you could pick who can actually see that you're on signal especially with a new number/phone. Lots of people are often a negative in your life.
But who knows, the private contact discovery is quite magical so maybe there’s a way….
