I believe that requirement ended. I had to get a different DNS at one point for my .is (registered in 2009) and I still maintain that account with DNSMadeEasy out of laziness), but when I helped a friend register a .is and when I got some additional ones more recently, I didn’t have to do that anymore. I believe Namecheap offloads some of the info for .is back to ISNIC. The only reason I don’t do it under Namecheap is that I’ve had the ISNIC account for 11 years and it’s easy enough to get my annual email reminding me to renew, but I was able to get my friend’s registered through her Namecheap account without issue at the end of last year.
