No means NO 🙅🏼

It turns out that Avrora.Config.registry_schemas_autoreg/0 configuration option was not returning false values if the library is configured and a private client is not used. And the only way to set it to false was to create your client and configure it like

defmodule MyClient do
  use Avrora.Client, registry_schemas_autoreg: false
end

Thanks to @ankhers it's fixed now! Enjoy folks! 🚢
