It's not a step backwards for me. Our organization uses signal in many situations where SMS isn't an option. When I land in a new country it is normal for my cell/SMS not to work. But I can hop on some local wifi and get signal messages. We had a widespread cell outage in my area last year. Signal not being on cell/SMS meant that I could still communicate with family without need of cell towers. This is a big step forwards imho.
