I get you re the phone number requirement, but that is indeed what has made it gain widespread adoption outside of tech communities - you do not need anything else, just a phone number.
It is very easy to "work around" the privacy implications, with about $10: pick your favorite VOIP provider, buy a number, register said number with signal (the SMS will not reach, but once it times out, you can instead receive an automated call.. you see the picture!).
Unfortunately the app does not support multiple profiles / registered numbers, which somewhat limits the effectiveness of this technique -- you could switch users (in android) for different numbers, but that does not scale either.
Group support has been there for a long time.

Great write up. Thank you!
Good to know that there's a workaround, but it's just a workaround :) I'd prefer a second more crypto function...
