A huge advantage to .feedback domains is that they come with a free optional SAAS platform that facilitates reviews within two minutes after registration. Visitors can give feedback on the website's address and also read reviews by other visitors. The service handles authentication of visitors with social media logins. The domain owner can login and make changes to the website in the control panel.
The registry hosts the DNS for the domains so that the registry can activate the SAAS platform. The hosted DNS records by the registry will have no interference with domain owners setting other records like MX, SRV, and TXT records. Just as with .com, the owner declares their name servers. Those name servers will be used to resolve MX, SRV, and TXT records in real time.
