missing end_session_endpoint from .well-known doc

[tech-sam]

I am using angular OIDC with hydra as my oauth2 server , angular oidc client accepting end_session_endpoint as a logout URL which will be acting as postLogoutRedirectUri so while loading well-known configuration end_session_endpoint is missing.
so post logout redirection is not working. Below is sample response for well-known document

Thanks, would you mind addressing this in a PR?

Ok, so I just checked with the spec and end_session_endpoint is a value from OpenID Connect Session Management 1.0 which is currently a draft and is thus not stable. We discussed implementing this spec a few times here but the general consensus was to wait until it's final, and also big question marks regarding some of the flows which use hidden iframes and other ugliness. As such, this feature will currently not be added as we don't want to implement something from a spec that's actually not supported.

Please raise an issue with the lib you're using for making this configurable or working towards a solution which enables you to consume this functionality without relying on the value. Thanks!
