Hi, I’m sorry but it doesn’t make sense to me (yet).
I have both relationship and post_object fields, with ‘return_format’ set to ‘object’. Calling get_field('field-name'); still returns the linked post(s) ID though.
What you’re saying is that in some cases you don’t need the whole post object, just the ID, in which case having the ID as return format would be sufficient, and faster. I don’t see how that is an answer, since both return formats return the ID, while neither of them return the post object?
