Ironically, this might be at least partially because the internal security controls at Cloudflare for using or provisioning new domains/subdomains is so difficult and arduous that the team decided the fastest way to go to market is to get an entirely new domain. Possible bonus that the official bug bounty program won't apply either, since it's on a new domain so any vulnerabilities found won't have to be paid out (as much).
