+1, that's the same way I see it (and what I considered "best 
practice"). The topic name can give you the semantics while the message 
gives you the syntax, i.e., just names what is stored in it (see e.g. 
PoseStamped or the "Empty" srv that is used for all kinds of tasks). 
Just call rename the fields "temperature", "illuminance", 
"fluid_pressure" etc to "value" and you have the same message definition.
