SQS event not containing Attributes field by design

[TomaszBorczyk]

I was looking into utilizing messageGroupId at the sensor level, since in our project we are using different group ids for various scenarios.
I wanted to extract it at the SQS sensor level, but then noticed it is not available. Digging deeper into argo implementation, I've noticed that whole SQS message Attributes field is omitted:

argo-events/eventsources/sources/awssqs/start.go

Line 149 in 6b44292

data := &events.SQSEventData{

even though it is available in the message itself:
https://docs.aws.amazon.com/sdk-for-go/api/service/sqs/#Message

is there any reason those fields are omitted? They contain information that is often important on the client side, like the group id and timestamps.

Is there any workaround for this, or should I duplicate this group id at the producer level to be also added to MessageAttributes?

Followup question: if messageGroupId is unavailable at both source level (#592) and sensor level (this issue), is there any way it can be utilized in argo?
