RDAP domain objects contain other information that can also be obtained in the DNS, such as nameservers, glue, and DS records. Evidently there is value in providing this information via an alternate channel (such as to debug DNS resolution issues). Providing TTL information via RDAP is consistent with that approach and will also be helpful in the same scenarios.
