Well, e.g., I've been wondering if folding this into autocomplete
could work. It already has a bunch of things that enable automation of
identity creation. We could add some more stuff to make federation

It's not entirely clear to me the federation abstraction works if the
browser cannot even guarantee to the user that the UI is actually
about a federation and not some other type of tracking data. Having
said that, the same probably goes for form autofilling to some extent.
