I think so yes, that is why I believe it is proposed in abfab. The draft
says:

"Inspired by the previous work, this document considers a use case
   which telecom operator acts as Identity provider (IdP) and federates
   with non-Web applications, e.g.  Email, Messaging."

So I think Yinxing proposes an abfab use-case.... but probably Yinxing
can better answer that himself....
