Should we add the Payment Request id to the signed SPC data (to facilitate connection between authentication and transaction)?

Hello,

Payment Request API creates a unique id for each transaction. That id is available when using SPC, but it is currently not included in the signed data with the transaction amount, merchant name, etc. It might be trivial to add.

Having the id would allow connections between the authentication data and a transaction where SPC was invoked. Would that be of value?
