>So now any change to one service required deploying that service and pulling down the OpenAPI spec to regenerate client bindings. It was so clumsy and easy to make simple mistakes.

Why? Is your framework heavily tied to client bindings? APIs I consume occasionally get new fields added to it for data I don't need. My code just ignores it. We also have a policy you cannot add a new mandatory field to API without version bump. So maybe REST API would have new field but I didn't send it and it happily didn't care.
