The advantage for me is having the ACF fields submitted and using those rather than a custom input. The other advantage for me is not building a table in a message field.
But, it would not reduce work. I’d have to dynamically load the ACF repeater. I’d have to make all the fields except the checkbox readonly. I still have to do all the processing. And then I would need to delete the repeater data that ACF saved after I was done processing. In the long run this would probably be more work to be honest. I’d also need to weigh that against I needed this and the time I have available to get the job done. And like I said, how many posts would be shown. Make a repeater too long and bad things can happen so I’d have to look at the possibility of the repeater growing too large.
