Investigate if event source filtering is useful

[DavidBoike]

In November 2021, AWS announced that AWS Lambda now supports event filtering for Amazon SQS, Amazon DynamoDB, and Amazon Kinesis as event sources.

It feels clear to me how this would be useful for Kinesis streams, as different lambdas could look at the same event stream, filter for different things, and act differently.

It seems less clear why this would be useful for SQS since an SQS message in a queue should be processed exactly once and the NServiceBus semantics would guarantee that selection of message handlers is already baked in.
