K, all makes sens to me know. I do the same thing. The only requirements for the field keys is that they are unique, don’t change and start with “field_” Generally I create field like “field_prefix000001”, “field_prefix000002”, etc. so I know they will never be the same as a key that ACF will ever create. Then like you said, you’re good to just use the ACF function to add field groups and fields.
