It would be great if we could create hosts/templates for the different sensors we are accessing using MQTT, however using agents for this, is kind of strange. Obviously we can't install agents on the hosts (they don't even have IP addresses, eg. LoRaWAN nodes), so the config is really convoluted right now.

It would be much easier if there would be an MQTT item type, and the server/proxy would connect to the MQTT broker and provide the values for it. It could use the host interfaces, or macros, etc for the broker address. Would make creating templates, and LLDs, and maps much easier.

This structure would make much more sense than the current agent-host based one.
