This would be awesome to have, because with the Swagger (now OpenAPI) spec published, the Zabbix API could be consumed by tools such as https://swagger.io/tools/swagger-codegen/ or https://github.com/Azure/autorest/.

The beauty of being able to use the above tools would be that every time a new version of Zabbix is released, you don't have to manually update whatever Zabbix API module you use.

e.g. I use psbbix to connect to Zabbix API using Powershell. I just finished scrolling through the list of API updates from 5.2 to 5.4, and it would mean A LOT of updates need to be done to the module. At least theoretically, if Zabbix published it's API spec in OpenAPI, I could just run the latest spec through the API code gen tool, and have an updated Powershell module, ready to take advantage of the latest updates to the API.
