I approach this from the other side. I always want to be completely in control over how a message gets sent because the different mechanisms all have unique failure reliability modes. If I want to send an SMS I go to the SMS app. If I want to send through Signal I go to Signal. That way I'm never surprised by my phone doing something unexpected like trying to use a flaky data stream instead of piggybacking on tower traffic or vice versa.
