I wasn’t aware of this but I have created an internal ticket to update the node to use the new API which we will be tracking as NODE-2031.
There is a good chance that when we do make this change some functionality will change but we will continue to support and allow the rest api to be used for as long as Shopify have it available.
I think they support REST API up to April 2025.
I have seen some communication around this few days ago… but I do not see anymore.
If I find more details I will share
