We have support for hardcoded claims as well as other claims. Here is an example of how we configure those in config/initializers/openid_connect_provider.rb

  config.add_scope OIDCProvider::Scopes::Profile do |account|
    name "#{account.first_name} #{account.last_name}"
    given_name account.first_name
    family_name account.last_name
  end

  config.add_scope OIDCProvider::Scopes::Email do |account|
    email account.email
    email_verified false
  end

Is that what you're referring to, or something else?

I am talking about the "claims" request parameter described in the OpenID documentation so that one can ask the OIDC provider to include this and that claim in the id_token because he will not call the /user_info endpoint (well this is my use case).

I am preparing a PR, I should submit it today.

It took more time than expected but it is now ready for code review! :)
