I see. But if we can think about at least of one "type" of the action,
which may not show any special page, there are probably others :)

It is pretty much OIDC flow. So:
- The initial request with "kc_action=link-facebook" is sent to OIDC
authentication endpoint
- KC (re-)authenticates user and do all the UI actions required for the
requested action
- Before the model is updated (EG.
userModel.addFederationLink("facebook") called), there is redirection to
client with code+state etc
- Client needs to send code-to-token request.
- KC will need to verify code (already done), finally finish the model
(EG. call "user.addFederationLink" or "user.setEmailVerified(true)" ).
That's where I think the SPI callback will be needed. Finally
re-generate tokens and verify back to the application.
- Client receives updated tokens with all the new state (EG.
"email_verified" is set to true, user's birthday claim retrieved from
facebook is in the token etc.)
This has some good advantages like the:
- Client is verified. In case of confidential clients, there is proper
client authentication. For public clients, there is at least redirection
back to the client application and exchanging for tokens, which is still
bit safer than just update model on server (EG.
userModel.addFederationLink) and redirect to client after. However for
public clients, people will more likely want to show the splash screen
"Application XY wants to link your account"
- Tokens are updated at the end of the flow. This is important for many
applications though as in many cases, people will likely trigger actions
under some conditions. For example in the application will do something
like:
if (!idToken.isEmailVerified()) {
redirectToVerifyEmailAction();
}
So without updated tokens, you will have infinite loop or the need to
re-trigger to OIDC flow manually again to have tokens refreshed with new
claims

I see. I am also not convinced so much about scope param... Just some
quick idea :)
