The point of "--only-trailers" is to give a caller an output that's easy for them to parse. Getting rid of the non-trailer material helps, but we still may see more complicated syntax like whitespace continuation. Let's add an option to unfold any continuation, giving the output as a single "key: value" line per trailer. As a bonus, this could be used even without --only-trailers to clean up unusual formatting in the incoming data.
