I'm currently pausing this work in favor of implementing a sessionhandler. To make the code review faster, we discussed as a team to copy the existing PRB implementation and then create a separate PR with the necessary modifications. The first PR to copy the implementation has been implemented: https://github.com/Automattic/woocommerce-payments/pull/8989

While working on this, I also noticed that the data store has a different data contract than the Store API. All the utilities in the tokenized cart leverage the Store API data contract. So we have two options:

• Modify the utilities to use both data contracts
• Massage the data from the data store into the Store API data contract

After consulting with the blocks team ( p1718815646160629-slack-C02TS23QJ1X ) , they recommended the second option - which is what I'll be going with.
