They should be sloping the pavers and adding appropriate drains that are piped to a good drainage location. Something like you see here (diagonally from the middle bottom of photo to the aluminum chair).
Also kudos to you for heading off the "You better get ARC approval" posts. I'm sure someone will still post how it won't be allowed or something. LOL
Edit to add: Tinker is correct. He is thinking of polymeric sand. It is much better than the old stone dust as it helps prevent weeds from growing through. It is almost impermeable to water. I have a low spot on my paver patio here in MA and it gets a puddle that is slow to drain away.
