title: OAuth 2.0/OpenID Connect: Get notification when user deleted from Identity provider
body: <p>Does OAuth2 and/or OpenID Connect have a feature to notify the client (e.g my app) about user deletions? If so is it part of the standard, or just some providers have it, some don’t?</p>
  <p>Let’s have an example:</p>
  <ol>
  <li>User registers in my app with his Github account (or any oauth2 id. Provider)</li>
  <li>Starts working, do changes and saves stuff</li>
  <li>Decides to delete his account from github.</li>
  </ol>
  <p>Does oauth2 have a mechanism for this scenario to somehow let my application know that ‘hey, this user deleted himself, clean up after him’?</p>
  <p>Another example could be this site. I registered with my Github account. How would StackOverflow know it needs to delete my comments once my github account is long gone?</p>
  <p>Thank you in advance!</p>
