In the beginning of my Node-RED time, I have used MQTT extensively.
If I now look at old flows, I am using MQTT mainly to connect flows within the same Node-RED instance.
I have the feeling that many other people do that as well.
It is somehow questionable if it is a sensible idea to use MQTT as a middleware to route messages within Node-RED.
Therefore, I would like to know what people think about a "link" node which behaves like an MQTT node with topics etc.
There would be a "link out" node, which would have a configurable topic property.
Then there would be a "link in" node, which could subscribe to a topic of the "link out" nodes, with wildcards etc. as in MQTT.
Does this make sense?
I also think it should be a new node and not an addition to the link node.
The advantage compared to a link node would be mainly wildcards and maybe a bit better organization.
