I don't have much expertise with Timestream. Can't comment on it. But, there is nothing wrong in trying for an alternate implementation. We're using Kinesis and it is a good fit in our stack with lot less overhead. They did bring Kakfa (Amazon MSK) later to the AWS service list. Its upto the consumer to pick Kinesis or MSK.

One example which was influential in nature - Dyanmodb. The Dyanmodb paper inspired a number of NoSQL databases, including Apache Cassandra. If they have went with the popular NoSQL database at that time, we might have missed some good contribution.
