It seems that in D7 the "settings" attribute is required for any feature definition, otherwise
Notice: Undefined index: settings in uc_product_feature_settings_form() is thrown. Is that so by design and what is the proper way to _not_ have settings in this scenario? I've set
'settings' => FALSE but I'm not sure if that's the most elegant/appropriate thing to do here.
Thanks in advance for your help.
