I happen to think that the trace output is primarily for machine
consumption (i.e. if you want to make it readable by humans, it is
OK to require them to pre-process).

How does this "duplicate output" come about?  If it is because
end-user configuration files have multiple entries that are either
list-valued or relying on last-one-wins semantics, I suspect that it
is better not to prematurely filter these at the trace generation
side (which by definition is an opration that loses information).

So, to me, it smells that the whole "dedup at the source" thing is
not just not worth the effort but is misguided.
