+# Adds a missing rake task for revoking SMS verifications.
+# Decidim is supposed to add this task in decidim-verifications/lib/tasks/revoke.rake
+# But this file is evaluated before the initializers have a chance to configure the
+# Decidim.sms_gateway_service (in our decidim initializer) and register the sms
+# verification workflow (in decidim-verifications/lib/decidim/verifications/sms/engine.rb)
+#
+# See https://github.com/decidim/decidim/issues/16546 where this bug is reported and tracked.
