I find that extremely interesting. For example, this is a field I created for a plugin for ACF4
array('key' => '_acf_key_acfop_menu', 'label' => 'Menu Text', 'name' => '_acfop_menu', 'type' => 'text', 'instructions' => 'Will default to title if left blank.', 'default_value' => '', 'placeholder' => '', 'prepend' => '', 'append' => '', 'formatting' => 'none', 'maxlength' => '')
I was thinking to myself… “It would be nice if all those fields didn’t appear in the ‘Custom Fields’ drop down in WP”… so I tried changing them to start with an underscore. When that worked I just started changing the “key” value to whatever I wanted and that worked.
If this is a bug in ACF4 I would ask that it’s a bug you ignore. 😛
