Flow with 10 MQTT "IN Node".. is better use just one "IN node" and split via "function node"?

@Semmu

everything branched out from that one single entry point, making my flows very ugly and messy and hard to follow, manage, etc

I'm a bit surprised you feel your flows are less messy, and easier to maintain, with a seperate config node and mqtt-in for each discrete topic.
What happens when you change your MQTT password?
Still, I can see the appeal of a discrete input point for each flow / section of a flow.

@Semmu

And it has no "real" performance impact, since it uses 1 MQTT connection (per config node)

This thread illustrates a problem with a particular cloud based broker service and one mqtt-in per topic.
