I'm not really sure what is commonly understood as "producing an EMF", but
it seems to me that every junction produces an EMF, and what we measure as
voltage is the addition of all the EMFs of all junctions between the two
points where we measure the voltage. No?

Is that really so? Say you have a junction and a capacitor with two plates
that are of the same material as the thermowires. I'm pretty sure the
capacitor gets loaded -- no second junction necessary.
