Currently you can filter products via a metafield both in the APIs and in Admin.
It would be really helpful to bring this functionality to other models in Shopify.
My specific request is for draft orders as currently I’m copying the data over between metafields and tags just to enable filtering which is more API requests for yourself and slows down the merchant experience.
The combined draft orders update endpoint is quite slow, taking over 2 seconds which isn’t ideal in use case, so I’m using the separate api endpoints in parralel to speed it up. However I’ve noticed a slow down in draft order creation now as well.
