We use OpenAPI in many other places too. Azure Logic Apps, Azure API Management, Azure Functions, Azure API Apps, Microsoft Flow, PowerApps. And the list just keeps getting longer. Also, the new Microsoft Docs site is driven off OpenAPI.
I believe at this time the majority of the azure sdks are using it, so quite an investment has been made.
