There has always been a lot of uncertainty over the future of Google Voice, given the lack of updates. While this does give reassurance that the project is still alive, it puts another nail in the Hangouts coffin. It was widely assumed Hangouts would subsume Google Voice, but now that looks very unlikely.
But really? I live in Europe and I'm still not able to order a Google Voice number... and god damn, I tried. I move between countries very regularly, having a single international number would be fantastic.
I've essentially stopped using hangouts anyway. Everybody I talked to on there is on Discord now (https://discordapp.com/). Screenshare and video calls coming soon to it too, at which point I'll permanently log off Hangouts. If I'm going to use a proprietary system, it might as well not suck.
