PayPal Express Checkout with REST API

I'm in the final stages of upgrading our store from 1.3.9h to 1.5.5f and notice the PayPal Express Checkout is using the deprecated NVP / SOAP interface.

I made a start on developing a new process flow utilising the recommended REST API but I would like to know if this is already being developed so I can jump on board to test and help where I can.

I'm not seeing any movement on this in the Core, so I'll be updating the code I developed back in 2018 to make use of the current PayPal checkout method, which looks pretty similar to the 2018 approach I took (now also deprecated).

Is there any current development to bring the Core to the 2022 recommended checkout method documented here: https://developer.paypal.com/docs/checkout/ ?
