So, for the layperson, who doesn't care whether their messages are encrypted or not, there's very little incentive to download this extra app and use it in addition to the default insecure SMS app.
I don't expect this to reach the Signal team's ears, and I don't have a clever solution in mind. They've made their decision and clearly communicated it, and I wish them luck. But over time, I'm probably going to stop using it. It's too much work.
I lament the loss of this boon to secure comm. 5/5
