Description

We publish explainers as issues per request from Mozilla (more details). For explainers please see the first and second comments of Error API, AccountAutoSelectedFlag, HostedDomain and Revocation.

Quick summary:
- With the Error API, the browser can inform users with proper error messages when their sign-in request has failed.
- With the AccountAutoSelected Flag API, the browser could help developers to determine if FedCM token requests were initiated with explicit user permission to improve their services.
- With the Hosted Domain API, RP can choose to only show the accounts which are associated with a certain domain.
- With the Revocation API, developers can revoke the connection between RP and IdP upon user request and update the browser to optimize the future flows.

We have spec PRs for Error API and AccountAutoSelectedFlag API since Chrome plans to ship them sooner than the other two.

Update: we also now have PRs for domain hint (renamed from hosted domain) and disconnect (renamed from revoke).

Closing in favor or #309 as we have never given a position of the actual FedCM spec.
