Is data loss possible when consume aggregated records by AWS lambda?

I've read the following warning from [this page ](https://www.npmjs.com/package/aws-kinesis-agg)

**Caution - this module is only suitable for low-value messages which are processed in aggregate. Do not use Kinesis Aggregation for data which is sensitive or where every message must be delivered, and where the KCL (including with AWS Lambda) is used for processing. [DATA LOSS CAN OCCUR.](https://github.com/awslabs/kinesis-aggregation/blob/potential_data_loss.md)**

But as I know, records are not consumed by KCL in lambda and need to be deaggregated manually by invoking `deaggregate`, Is it still possible data loss in this case?

Read the linked potential_data_loss.md warning first, then trace how AWS Lambda and KCL deliver aggregated Kinesis records before manual deaggregation with deaggregate. Confirm whether this consumption path can lose records and document the conclusion with the relevant conditions and evidence.
