It's a very good decision in my opinion and Paxful should follow them because It doesn't matter how careful you are, you could fall for these scams one way or another. I remember buying some cards from someone on Paxful, and he used to have +1000 positive reviews while only a couple negative and then, his cards were carded. I managed to do some digging to find out that he's involved in some carding forums.
Cards are just another payment mode like bank transfer , if we talk about scams or carded cards , a vendor always release btc , when they completely assure the cards balance is used by them only. Otherwise they dont pay . Also escrow facility keeps both the parties safe and gives a fair chance to everyone. i believe options like coinbaazar.com and paxful.com are still there who can actually provide this kind of service.
