This is news to me, I had no idea that they were working on something like this.
I like and dislike single sign-on. For end users I think it’s great, not having to remember so many passwords is a big win for them. Spending time working instead of spending it trying to work will always pay off. I also do not like the fact that with one authentication point you can gain access to a large amount of data, segregation is always a good thing with your data. But combining this with two-factor auth (which this can use) and maybe keeping your most sensitive systems away from it, I think you can get to a happy medium.
