Distinction between POS and Graphql Exchanges

[APIConsumer]

It seems like Shopify just aligned this behavior with this sudden change:

Unannounced POS Exchange Changes

This change came out of the blue for us and completely breaks how we handle to exchanges from the POS. We were not on the exchangesv2 hidden beta, and we were relying on the orders/edited webhook to watch for exchanges. Is anyone else impacted by this? Why is there not a one year deprecation period for API users as well?
