I think false. I have the same frustrations. When I had Google Voice without Hangouts, it was a buzz after I texted and a clear message that the 'message failed to be sent...retrying'. I was able to use the long press to resend immediately, view the message details or cancel the message. I really enjoyed the feedback I got with them. I've now upgraded to Hangouts and I can't tell in low-connectivity settings whether I need to intervene or not. I'd prefer some easy feedback messages which I can identify action on. I expect network failure...but I'm honestly worried when I see Hangouts/Google Voice/phone failure.
