Why the plugin does not populate the related "additional_data" that comes from Adyen via webhook?

[rihck]

We're adapting the plugin to handle AAR (Adyen Auto Rescue) and would be good to store the related additional_data adyen send to us during AAR process.

So I have a question, why this piece of code was build like this in a way to not store the "additional_data" from adyen? Is there a reason or just because it would not be used anywhere.

this.additionalData = null;
