Hi, the blog post author here. This is an experimental project, with all the caveats that go along with it.
It could definitely have the same fate as Persona. In fact, we face a bigger set of challenges than Persona - we need to not just figure out adoption curves, but standardization, nailing down the security story more firmly, and driving cross-browser and cross-platform support. Each of these on their own is a significant challenge.
But I would hope that some people get their hopes up. Sometimes it's worth it to get your hopes up even though you have no guarantee that it'll work out in the end. You can get your hopes up and still be pragmatic and grounded in reality.
