How would you suggest Signal allow you to communicate with your contacts without leaking the fact that both of you are Signal users? Should it just blackhole the message if the other number doesn't have an account?
I understand the unease about the notifications, but there are some hard tradeoffs between how you can store as little information as possible, remain as decentralized as possible, while getting the same benefits as centralized systems like Facebook.
I'm really of the opinion that a messenger similar to Signal but more centralized in the fashion of WhatsApp or even Facebook Messenger should exist, but I also understand why Signal works the way it does.
Suggestion: it should, at very least, not show a UI a notification "_ is now on signal!" As a nice to have, yes, it should blackhole a message until at least one reply happens.
