In The Netherlands, they are implementing a thing which gives the same advantages (i.e. disclose some attributes about yourself without disclosing unneeded data), but uses different technologies. It's called IRMA, you can find an overview here [1]. It can be combined with other applications to do cool stuff, e.g. with PostGuard [2] you can use identity-based encryption to be able to send an encrypted email to someone, but without the need to know their public key in advance, nor having to authenticate it. The drawback is that you have to trust a central server and a third party identity provider.
