@matthinz , we mainly use the test oidc controller for dev purpose, tested it and still work as expected.

Noticed that we still build the open_id_authorize_form like

identity-idp/app/forms/openid_connect_authorize_form.rb

Lines 62 to 74 in e67768f

	def initialize(params)
	@acr_values = parse_to_values(params[:acr_values], Saml::Idp::Constants::VALID_AUTHN_CONTEXTS)
	@vtr = parse_vtr(params[:vtr])
	SIMPLE_ATTRS.each { |key| instance_variable_set(:"@#{key}", params[key]) }
	@prompt ||= 'select_account'
	@scope = parse_to_values(params[:scope], scopes)
	@unauthorized_scope = check_for_unauthorized_scope(params)
	@biometric_comparison_required = params[:biometric_comparison_required].to_s == 'true'
	if verified_within_allowed?
	@duration_parser = DurationParser.new(params[:verified_within])
	@verified_within = @duration_parser.parse
	end

where biometric_comparison_required still needed. Not sure how vot is built, but guess this part is still needed.
